                                   terms:description """Lynx is about providing better services on compliance. The added value of the Lynx services revolve around a better processing of heterogenous, multilingual documents in the legal domain. Hence, the most important document is the Lynx Document.Lynx Documents may be grouped in Collections, and may be enriched with Annotations. Thus, the main entities to deal with are three:

Lynx Documents are the basic information units in Lynx: identified pieces of text.
Collections are groups of Lynx Documents with any logical relation. There may be one collection per use case, per jurisdiction, etc.
Annotations are enrichments of Lynx Documents, such as summaries, translation, recognized entities, etc.
Because most of the AI algorithms dealing with documents focus on text -manipulation of images, videos or tables is less developed-, the essence of a Lynx Document is its text version. Thus, the key element in a Lynx Document is an identified piece of text. This document can be annotated with an arbitrary number of metadata elements (creation date, author, etc.), and eventually structured for a minimally attractive visual representation.

Original documents are transformed as represented in the following figure: first, they are acquired by harvesters from their heterogeneous sources and formats, being structured and represented in a uniform manner. Then, they are enriched with annotations (such as named entities like persons, organisations, etc.).

This ontology has been made with the purpose of supporting the representation of Lynx Documents, e.g., any document related to compliance worth to be in a Legal Knowledge Graph. This specification serves as a data model for documents in the Lynx project.

In order to manipulate the data structures described in this work, we recommend using the library described in https://gitlab.com/superlynx/common/lynx_mvn.

Lynx Documents are in general compliant with the NIF (NLP NLP Interchange Format) specification. Other ontologies have been also considered as a reference: see a broad list in http://lynx-project.eu/data2/reference-ontologies."""@en ;
