Dear Barry (and All)
   after some months we are back since we did not receive any feedback
after our email (dated March 19th, here below) which replied to your
remarks.

Is there any follow up on the analysis of the URN:LEX specifications?

Thanks a lot for sending your considerations
best regards

   Pierluigi and Enrico

> On the other hand the use of the title is limited to the cases in which the title itself, rather than other formal parameters, is commonly used to refer to a legal act. In these cases the title is considered as an additional information that can be added to the formal parameters to facilitate the identification.

> so that the identification of the related document can be facilitated from a citation including the title only and no other formal parameter, thus limiting the set of documents actually retrieved.
>
> In our case the URN deduced from the citation is "urn:lex:it:state:consolidated.act;public.procurements” that matches a very little number of act URNs, probably only one.
> If the title is not used, the URN derived from the citation would be “urn:lex:it:state:consolidated.act” which would retrieve back all the existing consolidated acts (on immigration, on education, etc), therefore being not enough selective.

> The set of metadata suggested in the urn:lex specifications have been selected after having analyzed the legal citations in different jurisdictions: such metadata are those ones typically used to identify legal documents in different countries. Urn:lex only formalizes such metadata in a structure and a syntax.
> On the other hand, if such metadata are used in natural language citations within acts, legal doctrine articles, etc., in our opinion it means that this system is considered valid for identification. Moreover, all the legal digital archives we have analyzed make use of these metadata as primary keys for identifying legal documents.
> The main difference we have found is between common law and civil law countries.
> In civil law countries, citations are always made of formal parameters (type of the act, date or year, number).
> In common law countries, having a lower number of laws, the use of citation including the title of the act (i.e. Human Right Act 1998) is more frequent than the use of the number (Act 1998, chapter 42). In this case using the title in a URN can facilitate document identification from its citation (see above), therefore in the case of the example the urn suggested is "urn:lex:uk:state:act;human.right:1998-11-09;42”.
