4.2 Mapping regarding the RIF-FLD Speech Syntax with the XML Sentence structure

Note that if D requires the directive Dialect(D) as part of its syntax then this implies that any D-admissible document must have this directive. ?

A round-tripping from an admissible file into the a good dialect, D, is actually an excellent semantics-preserving mapping so you're able to a document in almost any code L with an excellent semantics-preserving mapping in the L-file back again to an admissible D-file. When you are semantically comparable, the first in addition to bullet-set off D-files doesn't have to be the same.

cuatro.step one XML to your RIF-FLD Code

RIF-FLD spends [XML1.0] because of its XML sentence structure. The fresh new XML serialization to own RIF-FLD are switching otherwise completely striped [ANF01]. A completely striped serialization views XML records while the stuff and you can splits all XML labels into class descriptors, entitled particular tags, and you can property descriptors, entitled part tags [TRT03]. I follow the traditions of using capitalized names for sorts of labels and you will lowercase labels to own role labels.

The all-uppercase classes in the EBNF of the presentation syntax, such as Formula, become XML Schema groups in Appendix XML Schema for FLD. They are not visible in instance markup. The other classes as well as non-terminals and symbols (such as Can be acquired or =) become XML elements with optional attributes, as shown below.

To own capacity for source, the first algorithms come over the top

The RIF serialization framework for the syntax of Section EBNF Grammar for the Presentation Syntax of RIF-FLD uses the following XML tags. While there is a RIF-FLD element tag for the Transfer directive and an attribute for the Dialect directive, there are none for the Foot and Prefix directives: they are handled as discussed in Section Mapping from the RIF-FLD Presentation Syntax to the XML Syntax.

Title out-of a great prefix isn’t of a keen XML feature, because it's addressed via preprocessing because discussed when you look at the Point Mapping of Non-annotated RIF-FLD Vocabulary.

The id and meta elements, which are expansions of the IRIMETA element, can occur optionally as the initial children of any Class element.

The XML syntax for symbol spaces uses the type attribute associated with the XML element Const. For instance, a literal in the xs:dateTime datatype is represented as 2007-11-23T-.

The xml:lang attribute, as defined by 2.12 Language Identification of XML 1.0 or its successor specifications in the W3C recommendation track, is optionally used to identify the language for the presentation of the Const to the user. It is allowed only in association with constants of the type rdf:plainLiteral. A compliant implementation MUST ignore the xml:lang attribute if the type of the Const is not rdf:plainLiteral.

This case shows an XML serialization to the algorithms from inside the Analogy step three. To possess most useful readability, i once more utilize the shortcut sentence structure discussed inside [RIF-DTB].

This section defines a normative mapping, ?fld, from the presentation syntax of Section EBNF Grammar for the Presentation Syntax of RIF-FLD to the XML syntax of RIF-FLD. The mapping is given via tables where each row specifies the mapping of a particular syntactic pattern in the presentation syntax. These patterns appear in the first column of the tables and the bold-italic symbols represent metavariables. The second column represents the corresponding XML patterns, which may contain applications of the mapping ?fld to these metavariables. When an expression ?fld(metavar) occurs in an XML pattern in the right column of a translation table, it should be understood as a recursive application of ?fld to the presentation syntax represented by the metavariable. The XML syntax result of such an application is substituted for the expression ?fld(metavar). A sequence of terms containing metavariables with subscripts is indicated by an ellipsis. A metavariable or a well-formed XML subelement is marked as optional by appending a bold-italic question mark, ?, to https://www.datingranking.net/chatki-review its right.
