This deliverable contains an initial version of the Data Management Plan for Lynx following the template proposed by the EC (Section 2). The document is complemented with a catalogue of datasets belonging to the regulatory and linguistic domains which have been initially identified (Section 3). A methodology for identifying datasets is first described, which includes a template spreadsheet for the metadata description. A CKAN-based Lynx data portal has been also published, with the intention of becoming a reference site for the search of compliance-related datasets. A strategy for the harmonisation of data models has also been given along with a first description of data models of reference (Section 4). Finally, an initial description of the Legal Knowledge Graph is made (Section 5). This document will be superseded in M18 by the final Data Management Plan, Deliverable 2.4.
