LexMeta, a metadata model for lexical resources
LexMeta follows the entity hierarchy for the representation of artistic or creative endavour proposed in the FRBR ontology, widely used in libraries, which we partially map to the two-level hierarchy for the representation of Lexical-Conceptual Resource (LCR) metadata proposed in Metashare, from where we inherit the terminology, and the definitions. These hierarchy levels, expressed as classes, are the following:
| FRBR class | Metashare class | LexMeta class | Definition |
|---|---|---|---|
| frbr:Work | Lexicographic work (LexBib Q41) | FRBR: An abstract notion of a creation; used to group different expressions (editions, versions) of the same work, and address statements that apply on work level. | |
| frbr:Expression | ms:LexicalConceptualResource | LCR (LexBib Q4) | MetaShare: A resource organised on the basis of lexical or conceptual entries (lexical items, terms, concepts, etc.) with their supplementary information (e.g., grammatical, semantic, statistical information, etc.) |
| frbr:Manifestation | ms:DatasetDistribution | LCR Distribution (LexBib Q24) | MetaShare: Any form with which a dataset is distributed, such as a downloadable form in a specific format (e.g., spreadsheet, plain text, etc.) or an API with which it can be accessed |
The entity Schemata for LexMeta LCR and LCR Distributions are aligned to those of the corresponding FRBR and Metashare classes (in other words, the LexBib class is a subclass of both). This has several implications:
- Properties that describe LCR content are attached to items of class LCR (LexBib Q4).
- Properties that describe the LCR distribution, e.g. a physical dictionay in book form, or an electronic dictionary in a dictionary web portal or as downloadable dataset, are attached to LCR Distribution (LexBib Q24) items.
- LCR Distribution (LexBib Q24) items, when they have publication metadata as books have, are LexBib Zotero items, i.e. in LexBib wikibase, members of class LexBib BibItem. This applies mainly to book publications, and distributions on CD-ROM. But also online electronic dictionaries are collected in library information systems and can have publication metadata, and can exist as LexBib Zotero items.
- A dictionary with the same contents in printed form, on CD-ROM, available in a mobile app, or downloadable in different serialization formats (XML, JSON, etc.) will be represented as the same LCR (LexBib Q4) with different distributions (LexBib Q24).
- Different versions, editions, conversions, summaries, etc., of a lexicographic work will be represented as different LCR (LexBib Q4) items, being able to describe relations between these using properties defined in Metashare.
Description of lexical-conceptual resources (LCR), such as dictionaries
LexMeta provides categories for classifying dictionaries and other lexical resources, here called properties attached to LCR. Properties and range (i.e., the datatype or class of items that is accepted as object of a property), are defined as listed in the following table.
Properties describing dictionary structure and type have certain concept schemes as range. See these schemes, together with their top concepts (which may have other terms as narrower concepts) using this Query.
Note: This is still in sandbox stage.

Description of LCR distributions, such as dictionaries distributed in printed or electronic form
Manuscript, printed, and offline and online electronic dictionary distributions are represented using the same set of properties as for LexBib metalexicographical articles. They can also be listed in LexBib Zotero. The following table lists properties that are attached to LCR distributions (Q24) specifically, and to bibliographical items (Q3) in general. Publication metadata properties are described in the BIBO ontology (RDF), and Zotero item data fields map to BIBO.
