LexMeta follows the three-level entity hierarchy for the representation of artistic or creative endavour proposed in the [https://vocab.org/frbr/core FRBR ontology], widely used in libraries, which we map to the two-level hierarchy for the representation of LCR metadata proposed in [https://github.com/ld4lt/metashare/blob/dev/metashare.owl Metashare], from where we inherit the terminology, and the definitions. These hierarchy levels, expressed as classes, are the following:

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:
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 [[Item:Q4|LexicalConceptualResource]].
* Properties that describe LCR content are attached to items of class [[Item:Q4|LexicalConceptualResource]].
* 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 [[Item:Q24|LCR Distribution]] items.
* 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 [[Item:Q24|LCR Distribution]] items.
* [[Item:Q24|LCR Distribution]] items, when they have publication metadata as books have, are [[LexBib Zotero]] items, i.e. in LexBib wikibase, members of class [[Item:Q3|LexBib BibItem]]. This applies mainly for 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. Publication metadata properties are described in the [http://bibliontology.com/ BIBO ontology] ([http://purl.org/ontology/bibo/ RDF]), and Zotero item data fields map to BIBO.

* 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 resource ([[Item:Q4|LexicalConceptualResource]]) with different distributions ([[Item:Q24|LCR Distribution]]).

* Different versions, editions, conversions, summaries, etc., of a lexicographic work will be represented as different [[Item:Q4|LexicalConceptualResource]] items, being able to describe relations between these using properties defined in Metashare.
