Add law authorities

[ppKrauss]

As described by Wiki, some organizations can be authorities, and like implemented at OpenGovLD/skos/terms.jsonld, some concepts are authority names or class of authorities. The suggestion is to expand to all kind of "legal power" officially used in European N-Lex, legislation.gov.uk, Brazilian LexML, etc.

Example: the Lex-URN inspired Brazilian's authority concept scheme at autoridade-rdf.xml (a SKOS-RDF file) lists all authorities of a statutory obligation norms-set of Brazilians federal government.

Concept of "law authority''... it is a "house of norms", examples:

• Generic concepts as Upper house or City council.
• Contry-specific names, as Federal Senate or Hauptausschuss.
• the actual authority issuing the legal provision. More specifically, the authority adopting the provision or enacting it;
• the institution where the provision is registered, known and referenced to, even if produced by others (e.g., the bills identified through the reference to the Chamber where they are presented);
• the institution regulated (and referred to in citations) by the legal provision even when this is issued by another authority (e.g., the statute of a Body);
• the entity that proposed the legal material not yet included in the institutional process (e.g. a proposed bill written by a political party).

@ppKrauss Thanks a lot for this suggestion, the links and the examples. I will have a close look early next year :)
