Implementation of SBML's UnitDefinition construct.
Units of measurement may be supplied in a number of contexts in an SBML model. The SBML unit definition facility uses two classes of objects, UnitDefinition and Unit. The approach to defining units in SBML is compositional; for example, meter second –2 is constructed by combining a Unit object representing meter with another Unit object representing second –2. The combination is wrapped inside a UnitDefinition, which provides for assigning an identifier and optional name to the combination. The identifier can then be referenced from elsewhere in a model. Thus, the UnitDefinition class is the container, and Unit instances are placed inside UnitDefinition instances.
Two points are worth discussing in the context of SBML units. First, unit declarations in SBML models are optional. The consequence of this is that a model must be numerically self-consistent independently of unit declarations, for the benefit of software tools that cannot interpret or manipulate units. Unit declarations in SBML are thus more akin to a type of annotation; they can indicate intentions, and can be used by model readers for checking the consistency of the model, labeling simulation output, etc., but any transformations of values implied by different units must be incorporated explicitly into a model.
Second, the vast majority of situations that require new SBML unit definitions involve simple multiplicative combinations of base units and factors. An example is moles per litre per second. What distinguishes these sorts of unit definitions from more complex ones is that they may be expressed without the use of an additive offset from a zero point. The use of offsets complicates all unit definition systems, yet in the domain of SBML, the real-life cases requiring offsets are few (and in fact, to the best of our knowledge, only involve temperature). Consequently, the SBML unit system has been consciously designed to simplify implementation of unit support for the most common cases in systems biology. The cost of this simplification is to require units with offsets to be handled explicitly by the modeler.
UnitDefinition has two attributes and one subelement. The two attributes are 'id' and 'name', and the subelement is ListOfUnits.
The required attribute 'id' and optional attribute 'name' are both strings. The 'id' attribute is used to give the defined unit a unique identifier by which other parts of an SBML model definition can refer to it. The 'name' attribute is intended to be used for giving the unit definition an optional human-readable name. Please see the next section for information about the values permitted for 'id'.
A UnitDefinition must contain exactly one ListOfUnits, and this list must contain one or more Unit definitions; see the definitions of these other object classes for more information about them. The following example illustrates a complete unit definition (when written in XML) when they all the pieces are combined together. This defines 'mmls' to be millimoles per litre per second. <listOfUnitDefinitions> <unitDefinition id="mmls"> <listOfUnits> <unit kind="mole" scale="-3"> <unit kind="litre" exponent="-1"> <unit kind="second" exponent="-1"> </listOfUnits> </unitDefinition> </listOfUnitDefinitions>
The attribute 'id' in UnitDefinition cannot be given simply any value, and the precise details of the values permitted differ slightly between Levels of SBML:
The 'id' of a UnitDefinition must not contain a value from the list of SBML's predefined base unit names (i.e., the strings gram
, litre
, etc.). In SBML Level 3, this list consists of the following:
ampere | farad | joule | lux | radian | volt |
avogadro | gram | katal | metre | second | watt |
becquerel | gray | kelvin | mole | siemens | weber |
candela | henry | kilogram | newton | sievert | |
coulomb | hertz | litre | ohm | steradian | |
dimensionless | item | lumen | pascal | tesla |
This list of predefined base units is nearly identical in SBML Level 2 Version 4, the exception being that Level 2 does not define avogadro
. SBML Level 2 Version 1 (and only this Level+Version combination) provides an additional predefined unit name, Celsius
, not available in Level 3. Finally, SBML Level 1 Versions 2–3 provide two more additional predefined unit names, meter
and liter
. This is explained in somewhat greater detail in the description of the Unit class.
In SBML Level 2 (all Versions), there is an additional set of reserved identifiers: substance
, volume
, area
, length
, and time
. Using one of these values for the attribute 'id' of a UnitDefinition has the effect of redefining the model-wide default units for the corresponding quantities. The list of special unit names in SBML Level 2 is given in the table below:
Identifier | Possible scalable units | Default units |
---|---|---|
substance | mole, item, gram, kilogram, dimensionless | mole |
volume | litre, cubic metre, dimensionless | litre |
area | square metre, dimensionless | square metre |
length | metre, dimensionless | metre |
time | second, dimensionless | second |
Also, SBML Level 2 imposes two limitations on redefining the predefined unit substance
, volume
, area
, length
, and time:
(1) The UnitDefinition of a predefined SBML unit can only contain a single Unit object within it. (2) The value of the 'kind' attribute in a Unit instance must be drawn from one of the values in the second column of the table above.
The special unit names substance
, volume
, area
, length
, and time
are not defined by SBML Level 3, which uses a different approach to setting model-wide inherited units.
The vast majority of modeling situations requiring new SBML unit definitions involve simple multiplicative combinations of base units and factors. An example of this might be moles per litre per second. What distinguishes these sorts of simpler unit definitions from more complex ones is that they may be expressed without the use of an additive offset from a zero point. The use of offsets complicates all unit definition systems, yet in the domain of SBML the real-life cases requiring offsets are few (and in fact, to the best of our knowledge, only involve temperature). Consequently, the SBML unit system has been consciously designed in a way that attempts to simplify implementation of unit support for the most common cases in systems biology.
As of SBML Level 2 Version 2, Unit no longer has the attribute called 'offset' introduced in SBML Level 2 Version 1. It turned out that the general case involving units with offsets was incorrectly defined, and few (if any) developers even attempted to support offset-based units in their software. In the development of Level 2 Version 2, a consensus among SBML developers emerged that a fully generalized unit scheme is so confusing and complicated that it actually impedes interoperability. SBML Level 2 Version 2, Version 3 and Version 4 acknowledge this reality by reducing and simplifying the unit system, specifically by removing the 'offset' attribute on Unit and Celsius
as a pre-defined unit.
The following guidelines suggest methods for handling units that do require the use of zero offsets for their definitions:
Handling Celsius. A model in which certain quantities are temperatures measured in degrees Celsius can be converted straightforwardly to a model in which those temperatures are in kelvin. A software tool could do this by performing a straightforward substitution using the following relationship: T kelvin = TCelsius + 273.15. In every mathematical formula of the model where a quantity (call it x) in degrees Celsius appears, replace x with xk+ 273.15, where xk is now in kelvin. An alternative approach would be to use a FunctionDefinition object to define a function encapsulating this relationship above and then using that in the rest of the model as needed. Since Celsius is a commonly-used unit, software tools could help users by providing users with the ability to express temperatures in Celsius in the tools' interfaces, and making substitutions automatically when writing out the SBML.
Other units requiring offsets. One approach to handling other kinds of units is to use a FunctionDefinition to define a function encapsulating the necessary mathematical relationship, then substituting a call to this function wherever the original quantity appeared in the model. For example, here is a possible definition for converting Fahrenheit to Celsius degrees: <functionDefinition id="Fahrenheit_to_kelvin"> <math xmlns="http://www.w3.org/1998/Math/MathML"> <lambda> <bvar><ci> temp_in_fahrenheit </ci></bvar> <apply> <divide> <apply> <plus> <ci> temp_in_fahrenheit </ci> <cn> 459.67 </cn> </apply> <cn> 1.8 </cn> </apply> </lambda> </math> </functionDefinition>
An alternative approach not requiring the use of function definitions is to use an AssignmentRule for each variable in Fahrenheit units. The AssignmentRule could compute the conversion from Fahrenheit to (say) kelvin, assign its value to a variable (in Kelvin units), and then that variable could be used elsewhere in the model.
Please consult the SBML specifications for more information about this and other issues involving units.

inherited |
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(XMLNode annotation) or SBase::setAnnotation(string annotation), this method allows other annotations to be preserved when an application adds its own data.

|
inherited |
Appends the given notes
to the 'notes' subelement of this object.
The content of notes
is copied.
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.

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.

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. LibSBML provides an object model and related interfaces for certain specific kinds of annotations, namely model history information and RDF content. See the ModelHistory, CVTerm and RDFAnnotationParser classes for more information about the facilities available.

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 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 names begin with BQB_

Returns the MIRIAM model 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 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. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM model qualifiers are represented using valueswhose names begin with BQB_

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.

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.

will return the string 'metre (exponent = 1, multiplier = 1, scale = 0) second (exponent = -2, multiplier = 1, scale = 0)'
or, if the optional parameter compact
is given the value true
, the string '(1 metre)^1 (1 second)^-2'
. This method may be useful for printing unit information to human users, or in debugging software, or other situations.

Removes itself from its parent.
If the parent was storing it as a pointer, it is deleted. If not, it is simply cleared (as in ListOf objects). Pure virutal, as every SBase element has different parents, and therefore different methods of removing itself. Will fail (and not delete itself) if it has no parent object. This function is designed to be overridden, but for all objects whose parent is of the class ListOf, the default implementation will work.

Removes the top-level element within the 'annotation' subelement of this SBML object with the given name and optional URI.
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.
Calling this method allows a particular annotation element to be removed whilst the remaining annotations remain intact.

Sets the value of the 'id' attribute of this UnitDefinition.
The string sid
is copied. Note that SBML has strict requirements for the syntax of identifiers. The following is a summary of the definition of the SBML identifier type
SId
, which defines the permitted syntax of identifiers. We
express the syntax using an extended form of BNF notation:
letter ::= 'a'..'z','A'..'Z' digit ::= '0'..'9' idChar ::= letter | digit | '_' SId ::= ( letter | '_' ) idChar*The characters
(
and )
are used for grouping, the
character *
"zero or more times", and the character
|
indicates logical "or". The equality of SBML identifiers is
determined by an exact character sequence match; i.e., comparisons must be
performed in a case-sensitive manner. In addition, there are a few
conditions for the uniqueness of identifiers in an SBML model. Please
consult the SBML specifications for the exact formulations.

Sets the value of the 'metaid' attribute of this object.
The string 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.

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.

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.

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
.

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.
