Container for an SBML document and interface for global operations on SBML documents.
LibSBML uses the class SBMLDocument as a top-level container for storing SBML content and data associated with it (such as warnings and error messages). The two primary means of reading an SBML model, SBMLReader.readSBML() and SBMLReader.readSBMLFromString(), both return a pointer to an SBMLDocument object. From there, callers can inquire about any errors encountered (e.g., using SBMLDocument.getNumErrors()), access the Model object, and perform other actions such as consistency-checking and model translation.
When creating fresh models programmatically, the starting point is typically the creation of an SBMLDocument object instance. The SBMLDocument constructor accepts arguments for the SBML Level and Version of the model to be created. After creating the SBMLDocument object, calling programs then typically call SBMLDocument.createModel() almost immediately, and then proceed to call the methods on the Model object to fill out the model's contents.
SBMLDocument corresponds roughly to the class Sbml defined in the SBML Level 2 specification and SBML in the Level 3 specification. It does not have a direct correspondence in SBML Level 1. (However, to make matters simpler for applications, libSBML creates an SBMLDocument no matter whether the model is Level 1, Level 2 or Level 3.) In its barest form, when written out in XML format for (e.g.) SBML Level 2 Version 4, the corresponding structure is the following:
<sbml xmlns='http://www.sbml.org/sbml/level2/version4' level='2' version='4'> ... </sbml>
SBMLDocument is derived from SBase, and therefore contains the usual SBase attributes (in SBML Level 2 and Level 3) of 'metaid' and 'sboTerm', as well as the subelements 'notes' and 'annotation'. It also contains the attributes 'level' and 'version' indicating the Level and Version of the SBML data structure. These can be accessed using the methods defined by the SBase class for that purpose.
One of the most important features of libSBML is its ability to perform SBML validation to ensure that a model adheres to the SBML specification for whatever Level+Version combination the model uses. SBMLDocument provides the methods for running consistency-checking and validation rules on the SBML content.
First, a brief explanation of the rationale is in order. In libSBML versions up to and including the version 3.3.x series, the individual methods for creating and setting attributes and other components were quite lenient, and allowed a caller to compose SBML entities that might not, in the end, represent valid SBML. This allowed applications the freedom to do things such as save incomplete models (which is useful when models are being developed over long periods of time). In the version 4.x series, libSBML is somewhat stricter, but still permits structures to be created independently and the results to be combined in a separate step. In all these cases, it means that a separate validation step is necessary when a calling program finally wants to finish a complete SBML document.
The primary interface to this validation facility is SBMLDocument's SBMLDocument.checkInternalConsistency() and SBMLDocument.checkConsistency(). The former verifies the basic internal consistency and syntax of an SBML document, and the latter implements more elaborate validation rules (both those defined by the SBML specifications, as well as additional rules offered by libSBML).
The checks performed by SBMLDocument.checkInternalConsistency() are hardwired and cannot be changed by calling programs, but the validation performed by SBMLDocument.checkConsistency() is under program control using the method SBMLDocument.setConsistencyChecks(). Applications can selectively disable specific kinds of checks that they may not be interested in, by calling SBMLDocument.setConsistencyChecks() with appropriate parameters.
These methods have slightly different relevance depending on whether a model is created programmaticaly from scratch, or whether it is read in from a file or data stream. The following list summarizes the possible scenarios.
Scenario 1: Creating a model from scratch. Before writing out the model,
Scenario 2: Reading a model from a file or data stream. After reading the model,
LibSBML provides facilities for limited translation of SBML between Levels and Versions of the SBML specifications. The method for doing is is setLevelAndVersion() . In general, models can be converted upward without difficulty (e.g., from SBML Level 1 to Level 2, or from an earlier Version of Level 2 to the latest Version of Level 2). Sometimes models can be translated downward as well, if they do not use constructs specific to more advanced Levels of SBML.
Calling SBMLDocument.setLevelAndVersion() will not necessarily lead to a successful conversion. The method will return a boolean value to indicate success or failure. Callers must check the error log (see next section) attached to the SBMLDocument object after calling SBMLDocument.setLevelAndVersion() in order to assess whether any problems arose.
If an application is interested in translating to a lower Level and/or Version of SBML within a Level, the following methods allow for prior assessment of whether there is sufficient compatibility to make a translation possible:
Some changes between Versions of SBML Level 2 may lead to unexpected behaviors when attempting conversions in either direction. For example, SBML Level 2 Version 4 relaxed the requirement for consistency in units of measurement between expressions annd quantities in a model. As a result, a model written in Version 4, if converted to Version 3 with no other changes, may fail validation as a Version 3 model because Version 3 imposed stricter requirements on unit consistency.
Other changes between SBML Level 2 and Level 3 make downward conversions challenging. In some cases, it means that a model converted to Level 2 from Level 3 will contain attributes that were not explicitly given in the Level 3 model, because in Level 2 these attributes may have been optional or have default values.
Upon reading a model, SBMLDocument logs any problems encountered while reading the model from the file or data stream. The log contains objects that record diagnostic information about any notable issues that arose. Whether the problems are warnings or errors, they are both reported through a single common interface involving the object class SBMLError.
The methods SBMLDocument.getNumErrors(), SBMLDocument.getError() and SBMLDocument.printErrors() allow callers to interact with the warnings or errors logged. Alternatively, callers may retrieve the entire log as an SBMLErrorLog object using the method SBMLDocument.getErrorLog(). The SBMLErrorLog object provides some alternative methods for interacting with the set of errors and warnings. In either case, applications typically should first call SBMLDocument.getNumErrors() to find out if any issues have been logged after specific libSBML operations such as the ones discussed in the sections above. If they have, then an application will should proceed to inspect the individual reports using either the direct interfaces on SBMLDocument or using the methods on the SBMLErrorLog object.

appendAnnotation(XMLNode annotation)
Appends the given annotation
to the 'annotation' subelement of this object.
Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.
SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.
Unlike SBase.setAnnotation() or SBase.setAnnotation(), this method allows other annotations to be preserved when an application adds its own data.

Python method signature(s):
checkConsistency(SBMLDocument self)long
Performs consistency checking and validation on this SBML document.
If this method returns a nonzero value (meaning, one or more consistency checks have failed for SBML document), the failures may be due to warnings or errors.

For example, suppose a Model contains a FunctionDefinition with identifier 'f'
representing the math expression: f(x, y) = x * y. Suppose further that there is a reaction in which the <math>
element of the KineticLaw object contains f(s, p)
, where s

Removes InitialAssignment constructs from the document and replaces them with appropriate values.
For example, suppose a Model contains a InitialAssignment to a symbol 'k'
where 'k'
is the identifier of a Parameter. The outcome of invoking this method is that the 'value' attribute of the Parameter definition is set to the result calculated using the InitialAssignment object's <math>
formula, and the corresponding InitialAssignment is then removed from the Model.
True

XMLNode
Returns the content of the 'annotation' subelement of this object as a tree of XMLNode objects.
Whereas the SBML 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.
SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.
The annotations returned by this method will be in XML form.

Some changes between Versions of SBML Level 2 may lead to unexpected behaviors when attempting conversions in either direction. For example, SBML Level 2 Version 4 relaxed the requirement for consistency in units of measurement between expressions annd quantities in a model. As a result, a model written in Version 4, if converted to Version 3 with no other changes, may fail validation as a Version 3 model because Version 3 imposed stricter requirements on unit consistency.

Python method signature(s):
getMetaId(SBase self)string
Returns the value of the 'metaid' attribute of this object.
The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. (Importantly, this uniqueness criterion applies across any attribute with type XML ID, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use XML ID.) The 'metaid' value serves to identify a model component for purposes such as referencing that component from metadata placed within 'annotation' subelements.

Returns the Model object stored in this SBMLDocument.
It is important to note that this method does not create a Model instance. The model in the SBMLDocument must have been created at some prior time, for example using SBMLDocument.createModel() or SBMLDocument.setModel(). This method returns None

getNotes(SBase self)XMLNode getNotes(SBase self)
XMLNode
Returns the content of the 'notes' subelement of this object as a tree of XMLNode objects.
The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.
The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker.hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.
The 'notes' element content returned by this method will be in XML form, but libSBML does not provide an object model specifically for the content of notes. Callers will need to traverse the XML tree structure using the facilities available on XMLNode and related objects. For an alternative method of accessing the notes, see getNotesString().

getResourceBiologicalQualifier(SBase self, string resource)long
Returns the MIRIAM biological qualifier associated with the given resource.
In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The latter kind is used to qualify the relationship between a model component and a biological entity which it represents. Examples of relationships include 'is' and 'has part', but many others are possible. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify biological annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM biological qualifiers are represented using valueswhose names begin with BQB_
in the interface class libsbml.
This method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have biological qualifiers, looks for an annotation to the given resource
. If such an annotation is found, it returns the type of biological qualifier associated with that resource as a valuewhose name begins with BQB_

In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The former kind is used to qualify the relationship between a model component and another modeling object. An example qualifier is 'isDerivedFrom', to indicate that a given component of the model is derived from the modeling object represented by the referenced resource. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify model annotations in the same standardized way.

getSBMLDocument(SBase self)SBMLDocument getSBMLDocument(SBase self)
SBMLDocument
Returns the SBMLDocument object containing this object instance.
LibSBML uses the class SBMLDocument as a top-level container for storing SBML content and data associated with it (such as warnings and error messages). An SBML model in libSBML is contained inside an SBMLDocument object. SBMLDocument corresponds roughly to the class SBML defined in the SBML Level 3 and Level 2 specifications, but it does not have a direct correspondence in SBML Level 1. (But, it is created by libSBML no matter whether the model is Level 1, Level 2 or Level 3.)
This method allows the caller to obtain the SBMLDocument for the current object.

getSBOTerm(SBase self)int
Returns the integer portion of the value of the 'sboTerm' attribute of this object.
Beginning with SBML Level 2 Version 3, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int
, and SBO identifiers are stored simply as integers. (For convenience, libSBML offers methods for returning both the integer form and a text-string form of the SBO identifier.)
SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. Please consult the SBML Level 2 Version 4 specification for more information about the use of SBO and the 'sboTerm' attribute.

By default, all validation checks are applied to the model in an SBMLDocument object unless SBMLDocument.setConsistencyChecks() is called to indicate that only a subset should be applied. Further, this default (i.e., performing all checks) applies separately to each new SBMLDocument object created. In other words, each time a model is read using SBMLReader.readSBML(), SBMLReader.readSBMLFromString(), or the global functions readSBML() and readSBMLFromString(), a new SBMLDocument is created and for that document, a call to SBMLDocument.checkConsistency() will default to applying all possible checks. Calling programs must invoke SBMLDocument.setConsistencyChecks() for each such new model if they wish to change the consistency checks applied.

) |
Python method signature(s):
setConsistencyChecksForConversion(SBMLDocument self, long category, bool apply)
Controls the consistency checks that are performed when SBMLDocument.setLevelAndVersion() is called.
This method works by adding or subtracting consistency checks from the set of all possible checks that may be performed to avoid conversion to or from an invalid document. This method may need to be called multiple times in order to achieve the desired combination of checks. The first argument (category
) in a call to this method indicates the category of consistency/error checks that are to be turned on or off, and the second argument (apply
, a boolean) indicates whether to turn it on (value of True
) or off (value of False
).
The possible categories (values to the argument category
) are the set of constants whose names begin with the characters LIBSBML_CAT_
in the interface class libsbml. The following are the possible choices:
LIBSBML_CAT_GENERAL_CONSISTENCY: Correctness and consistency of specific SBML language constructs. Performing this set of checks is highly recommended.

args | |||
) |
Python method signature(s):
setLevelAndVersion(SBMLDocument self, long level, long version, bool strict=True)bool setLevelAndVersion(SBMLDocument self, long level, long version)
bool
Sets the SBML Level and Version of this SBMLDocument instance, attempting to convert the model as needed.
This method is the principal way in libSBML to convert models between Levels and Versions of SBML. Generally, models can be converted upward without difficulty (e.g., from SBML Level 1 to Level 2, or from an earlier Version of Level 2 to the latest Version of Level 2). Sometimes models can be translated downward as well, if they do not use constructs specific to more advanced Levels of SBML.
Before calling this method, callers may check compatibility directly using the methods SBMLDocument.checkL1Compatibility(), SBMLDocument.checkL2v1Compatibility(), SBMLDocument.checkL2v2Compatibility(), SBMLDocument.checkL2v3Compatibility(), SBMLDocument.checkL2v4Compatibility(), and SBMLDocument.checkL3v1Compatibility().
The valid combinations of SBML Level and Version as of this release of libSBML are the following:
Strict conversion applies the additional criteria that both the source and the target model must be consistent SBML. Users can control the consistency checks that are applied using the SBMLDocument.setConsistencyChecksForConversion() method. If either the source or the potential target model have validation errors, the conversion is not performed. When a strict conversion is successful, the underlying SBML object model is altered to reflect the new level and version. Thus, information that cannot be converted (e.g. sboTerms) will be lost.
level | the desired SBML Level |
version | the desired Version within the SBML Level |

The string metaid
is copied. The value of metaid
must be an identifier conforming to the syntax defined by the XML 1.0 data type ID. Among other things, this type requires that a value is unique among all the values of type XML ID in an SBMLDocument. Although SBML only uses XML ID for the 'metaid' attribute, callers should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement.

This method has multiple variants that differ in the arguments they accept. Each is described separately below.
Method variant with the following signature:
setNotes(string notes, bool addXHTMLMarkup = false)
Sets the value of the 'notes' subelement of this SBML object to a copy of the string notes
.
The content of notes
is copied, and any existing content of this object's 'notes' subelement is deleted.
The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.
The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker.hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.
The following code illustrates a very simple way of setting the notes using this method. Here, the object being annotated is the whole SBML document, but that is for illustration purposes only; you could of course use this same approach to annotate any other SBML component.
notes | an XML string that is to be used as the content of the 'notes' subelement of this object |

setSBOTerm(SBase self, int value)int setSBOTerm(SBase self, string sboid)
int
This method has multiple variants that differ in the arguments they accept. Each is described separately below.
Method variant with the following signature:
setSBOTerm(int value)
Sets the value of the 'sboTerm' attribute.
Beginning with SBML Level 2 Version 3, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int
, and SBO identifiers are stored simply as integers.
SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. Please consult the SBML Level 2 Version 4 specification for more information about the use of SBO and the 'sboTerm' attribute.

Method variant with the following signature:
setSBOTerm(string &sboid)
Sets the value of the 'sboTerm' attribute by string.
Beginning with SBML Level 2 Version 3, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int
, and SBO identifiers are stored simply as integers. This method lets you set the value of 'sboTerm' as a complete string of the form 'SBO:NNNNNNN', whereas setSBOTerm(int value) allows you to set it using the integer form.
SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'.

Python method signature(s):
unsetAnnotation(SBase self)int
Unsets the value of the 'annotation' subelement of this SBML object.
Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.
SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

Python method signature(s):
unsetId(SBase self)int
Unsets the value of the 'id' attribute of this SBML object.
Most (but not all) objects in SBML include two common attributes: 'id' and 'name'. The identifier given by an object's 'id' attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of 'id' is always either Sid
or UnitSId
, depending on the object in question. Both data types are defined as follows:
letter ::= 'a'..'z','A'..'Z' digit ::= '0'..'9' idChar ::= letter | digit | '_' SId ::= ( letter | '_' ) idChar*
The equality of SId
and UnitSId
type values in SBML is determined by an exact character sequence match; i.e., comparisons of these identifiers must be performed in a case-sensitive manner. This applies to all uses of SId
and UnitSId
.

Python method signature(s):
unsetMetaId(SBase self)int
Unsets the value of the 'metaid' attribute of this SBML object.
The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. (Importantly, this uniqueness criterion applies across any attribute with type XML ID, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use XML ID.) The 'metaid' value serves to identify a model component for purposes such as referencing that component from metadata placed within 'annotation' subelements.

Python method signature(s):
unsetName(SBase self)int
Unsets the value of the 'name' attribute of this SBML object.
Most (but not all) objects in SBML include two common attributes: 'id' and 'name'. In contrast to the 'id' attribute, the 'name' attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of 'name' is the type string
defined in XML Schema. SBML imposes no restrictions as to the content of 'name' attributes beyond those restrictions defined by the string
type in XML Schema.
The recommended practice for handling 'name' is as follows. If a software tool has the capability for displaying the content of 'name' attributes, it should display this content to the user as a component's label instead of the component's 'id'. If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the 'name' attribute is missing on a given component, then the user interface should display the value of the 'id' attribute instead. (Script language interpreters are especially likely to display 'id' instead of 'name'.)
As a consequence of the above, authors of systems that automatically generate the values of 'id' attributes should be aware some systems may display the 'id''s to the user. Authors therefore may wish to take some care to have their software create 'id' values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the 'id' attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of 'id' values, there are no restrictions on the uniqueness of 'name' values in a model. This allows software applications leeway in assigning component identifiers.
