An Ontology of Open Government Data Licenses Framework for a Mash up Model (OGDL4M) Introduction - martynui/OGDL4M GitHub Wiki

Welcome to the OGDL4M introduction site.

What it is? OGDL4M is a legal ontology, designed to deal with legal issues coming from mashups of Open Government Datasets. It represent a model, which deals with different licenses, different legal notices and legal norms applied to datasets released by Public Sector. It represents knowledge coming from EU PSI Directives (2003 and 2013), EU Database Directive, explains basic model how legal rules applies to datasets, connects copyright ontology.

Why we need that? Stakeholders of Open Data coming from Public Sector need to deal with legal issues applied to datasets. This ontology could be used to develop tools of automatic legal rules check, reuse of data conditions check, mashup possibilities check, automatic generation of Adapters license - it is a key element for Linked Open Government Data.

Do we really need that? Yes, our legal investigation discovered, that single Open License is a myth in global OGD domain. For example, in Spain reusers of OGD could be charged up to 100000EUR for violations of reuse rules. The ontology is a great tool to represent all risks and legal requirements applied to OGD in conceptual way, in machine understandable way.

Status of OGDL4M At the moment sole lawyers job is completed. It still need to be re-checked by computer scientist, ontology specialist. Joint work of lawyer and computer scientist is needed to make it a formal ontology.

Open Questions Legal domain otologies are so much jurisdiction and valid time depended. It need to be frequently updated by crowdsource. Legal norms should be published in xml format, it helped to highlight not updated parts of the ontology. Ontology is time depended, so it should be used by choosing the right version of the ontology, which has been valid in specific time period.
