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 | dcat:DatasetSeries (discussion ongoing) | Lexicographic work (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 (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 (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 LexMeta class is a subclass of both). This has several implications:
- Properties that describe LCR content are attached to items of class LCR (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 (Q24) items, when they have publication metadata as books have, are LexBib Zotero items, i.e. in LexBib wikibase, members of class BibItem (Q3. 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 (Q4) with different distributions (Q24).
- Different versions, editions, conversions, summaries, etc., of a lexicographic work will be represented as different LCR (Q4) items, being able to describe relations between these using properties defined in Metashare.
Note: This is ongoing work.
Description of lexicographical works
LexMeta provides this class for lexicographic work records in the catalogue, in parallel to what libraries do (example from DNB). Such records are used for grouping LCR as different expressions of the same work. Identifying and provenance metadata can be attached to work items. See an example record.

Description of lexical-conceptual resources (LCR), such as dictionaries
On the level of class frbr:Expression, libraries don't typically collect item records (they are focused on publication metadata, i.e. in LexMeta terms, distribution level). Expression is the level where metadata describing a resource's content corresponds to. For LCR records, LexMeta provides properties for classifying dictionaries and other lexical resources. The properties and their datatype or range of items that is accepted as object), 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 relate to other terms as narrower concepts) using this Query.

Description of LCR distributions, such as dictionaries distributed in printed or electronic form
Manuscript, printed, and offline and online electronic dictionary distributions as publications are represented in LexBib using the same set of properties as for metadata of bibliographical items (Q3) in general, including metalexicographical article metadata. Dictionary distributions can also be listed in LexBib Zotero. One property is specific to to LCR distributions (Q24): distribution type (P91), which takes values from the LCR Distribution Type concept scheme (Q43).
Most publication metadata properties are described in the BIBO ontology (RDF), which re-uses Dublin Core Terms.
