Utilized repeatedly within the rest of SBML Level two. three. Primitive data kinds
Made use of repeatedly in the rest of SBML Level 2. three. Primitive data forms Most primitive forms in SBML are taken in the information forms defined in XML Schema .0 (Biron and Malhotra, 2000; Fallside, 2000; Thompson et al 2000). Some other primitive forms are defined by SBML itself. What follows is usually a Echinocystic acid web summary from the XML Schema sorts along with the definitions of the SBMLspecific forms. Note that though we’ve got tried to supply correct and total summaries of the XML Schema forms, the following ought to not be taken to be normative definitions of those types. Readers ought to seek advice from the XML Schema .0 specification for the normative definitions of your XML sorts applied by SBML. 3.. Sort stringThe XML Schema .0 variety string is utilized to represent finitelength strings of characters. The characters permitted to seem in XML Schema string consist of all Unicode characters (Unicode Consortium, 996) except for two delimiter characters, 0xFFFE and 0xFFFF (Biron and Malhotra, 2000). Moreover, the following quoting guidelines specified by XML for character data (Bray et al 2000) have to be obeyed: The ampersand ( ) character have to be escaped working with the entity amp;. The apostrophe and quotation mark characters must be escaped using the entities apos; and quot;, respectively, when these characters are utilized to delimit a string attribute value.Author Manuscript Author Manuscript Author Manuscript Author ManuscriptOther XML builtin character or entity references, e.g lt; and xA;, are permitted in strings. three..2 Variety booleanThe XML Schema .0 type boolean is used as the data variety for SBML object attributes that represent binary truefalse values. XML Schema .0 defines the possible literal values of boolean because the following: ” true”, ” false”, ” “, and ” 0″. The value ” ” maps to ” true” along with the value ” 0″ maps to ” false”. Note that there’s a discrepancy amongst the worth spaces of variety boolean as defined by XML Schema .0 and MathML: the latter uses only ” true” and ” false” to represent boolean values and ” 0″ and ” ” are interpreted as numbers. Software tools ought to take care to not to use ” 0″ and ” ” as boolean values in MathML expressions. See further in Section 3.four.4. three..3 Form intThe XML Schema .0 type int is utilized to represent decimal integer numbers in SBML. The literal representation of an int is really a finitelength sequence of decimal digit characters with an optional leading sign (” ” or ” “). When the sign is omitted, ” ” is assumed. The value space of int could be the identical as a regular 32bit signed integer in programming languages such as C, i.e 247483647 to 247483648.J Integr Bioinform. Author manuscript; offered in PMC 207 June 02.Hucka et al.Page3..4 Type positiveIntegerThe XML Schema .0 sort positiveInteger is utilised to represent nonzero, nonnegative, decimal integers: i.e , 2, 3, …. The literal representation of an integer is a finitelength sequence of decimal digit characters, optionally preceded by a constructive sign (” “). There is no restriction around the absolute size of positiveInteger values in XML PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/23814047 Schema; having said that, the only situations exactly where this kind is made use of in SBML involve very lownumbered integers. Consequently, applications may possibly safely treat positiveInteger as unsigned 32bit integers. 3..5 Type doubleThe XML Schema .0 sort double may be the information kind of floating point numerical quantities in SBML. It can be restricted to IEEE doubleprecision 64bit floating point form IEEE 754985. The worth space of double consists of (a) the numerical values m 2x, where m is an integer whose.
