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-stumbling away from a keen admissible file into the a good dialect, D, is a beneficial semantics-sustaining mapping to a document in just about any vocabulary L accompanied by an excellent semantics-preserving mapping from the L-file to a keen admissible D-file. When you find yourself semantically similar, the initial while the round-trigger D-documents doesn’t have to be similar.
4.1 XML to the RIF-FLD Code
RIF-FLD uses [XML1.0] because of its XML sentence structure. The newest XML serialization to possess RIF-FLD try changing or fully striped [ANF01]. A totally striped serialization views XML data once the things and divides every XML tags with the category descriptors, titled style of labels, and you may possessions descriptors, titled part labels [TRT03]. I stick to the community of employing capitalized brands to own style of https://datingranking.net/tr/telegraph-dating-inceleme/ labels and you may lowercase names to own part tags.
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 capability of reference, the first formulas come ahead
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 Ft and Prefix directives: they are handled as discussed in Section Mapping from the RIF-FLD Presentation Syntax to the XML Syntax.
The name regarding an effective prefix isn’t from the an enthusiastic XML function, since it is managed via preprocessing since the discussed when you look at the Part Mapping of your own Non-annotated RIF-FLD Language.
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
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 example shows an XML serialization with the formulas from inside the Example step 3. For ideal readability, we again use the shortcut syntax defined from inside the [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 its right.
