ISO 24613-5-2022 pdf free download – Language resource management — Lexical markup framework (LMF) — Part 5: Lexical base exchange (LBX) serialization.
4 General requirements
This document aims at providing constructs for each LMF class from ISO 24613-1 (core model),ISO 24613-2 (MRD extension), and ISO 24613-3 (etymological extension). It requires compliance with ISO 24613-1, ISO 24613-2, and ISO 24613-3 when implementing data categories referred to in the respective parts, and compliance with the W3C XML Schema 1.1 for representing structured information in XML. LBX extends the original models by means of data category selections and precise value lists, the creation of new subclasses and the definition of new constraints. In addition, this document complies with the cardinalities expressed in ISO 24613-1, ISO 24613-2, and ISO 24613-3. The LBX serialization is richer in detail than LMF, in order to meet specific design objectives. Still, this document does not elaborate on the metadata aspects from LMF, since the LBX schema is by essence much richer for the representation of all the aspects related to the creation, content, versioning and database implementation of lexical content at large. Occasionally, slightly equivalent constructs to explicit requirements from the LMF standard are mentioned. The XML examples in this document are simplified by omitting namespaces. Except where otherwise stated, it is assumed that XML elements belong to the LBX namespace and that the examples lie within the scope of the following XML namespace declaration: xmlns=”http:// www .LexicalBaseExchange .org/ 2021/ schema” Besides, datatypes in this document are defined in compliance to the XML Schema Part 2 recommendation. The “xs:” prefix corresponds to the following namespace: http:// www .w3 .org/ 2001/ XMLSchema
5 Serialization of the LMF core model (ISO 24613-1) 5.1 Implementing the LexicalResource class The LexicalResource class shall be implemented in LBX by means of the <LexicalResource> element (see Table 1), which groups together one to many lexicons in a single collection. This level may be omitted in cases where the lexical resource contains only one lexicon so that the resource starts directly with the lexicon level. In cases where a lexical resource contains a large number of lexicons or several very large lexicons, the lexicon (XML document) can reference a virtual lexical resource using a @lexicalResourceID in the <Lexicon> element and optionally the <LexicalEntry> element (see 5.5).
5.2 Implementing the GlobalInformation class The GlobalInformation class shall be implemented in LBX by means of the <GlobalInformation> element (see Table 2) either by referencing a GlobalInformation.xsd schema using an <xsd: include> element, or as a direct child of a <LexicalResource> element. <GlobalInformation> allows the encoding of a variety of administrative, technical, documentary, and bibliographic information attached to the corresponding lexical resource.
5.3 Implementing the Lexicon class The Lexicon class shall be implemented in LBX by means of the <Lexicon> element (see Table 3), which is a direct child of the <LexicalResource> element when <LexicalResource> is used. If the <LexicalResource> element is not used, <Lexicon> becomes the root element. In cases where a lexical resource contains a large number of lexicons or several very large lexicons, the lexicon (XML document) can reference a virtual lexical resource using a @lexicalResourceID in the <Lexicon> element (see 5.1). In the case of a virtual lexical resource, where the <LexicalResource> element is not part of the same XML document as the <Lexicon> element, the lexicon can use an include statement to reference a relevant <GlobalInformation> element. Other information within the <Lexicon> element should be qualified through the following child element(s) and attributes as direct children of the <Lexicon> element or, optimally, as children of the <LexiconInformation> element (see 5.4):
