URI-URL and fragments

[monica.palmirani <monica.palmirani@unibo.it>]

Today in the LegalDocML TC we discussed the fragment syntax in the Akoma 
Ntoso URI. Fragment definition see http://tools.ietf.org/html/rfc3986

There are two problems:

a) fragment type document: Grant uses fragment type document <fragment> 
for fragmenting the US CODE in different physical files but logically 
belonging to the same unique work and expression (positive law titles 
are work).

The problems:
a.1.) how to nominate the manifestation level of the <fragment> file?
<fragment> exist only at manifestation level
For this reason the fragment work, expression, manifestation are the follow:
/akn/us/act/uscode/title9/ is the work
/akn/us/act/uscode/title9/eng@2014-01-10/ is the expression
/akn/us/act/uscode/title9/eng@2014-01-10/main.akn#chp_3 is the manifestation

a.2.) Section 301 belongs to this file.
A reference to sec_301 in the XML file is in this format:
/akn/us/act/uscode/title9/eng@2014-01-10/main.akn#chp_3__sec_301
however the fragment part of the URI chp_3__sec_301 can be lost in the 
HTTP protocol
For this reason Grant convert it in:
<a 
href="www.usc.grantresolver.gov/akn/us/act/uscode/title9/eng@2014-01-10/main.akn~chp_3__sec_301"> 
for not lost the fragment part (chp_3__sec_301).

When the resolver receives this URI 
www.usc.grantresolver.gov/akn/us/act/uscode/title9/eng@2014-01-10/main.akn~chp_3__sec_301, 
it understands which physical <fragment> file to dereference using the 
chp_3__sec_301

The problem is that: if the reference comes from external legal sources 
written in native Akoma Ntoso syntax 
www.usc.grantresolver.gov/akn/us/act/uscode/title9/eng@2014-01-10/main.akn#chp_3__sec_301 

the resolver has not change to understand the chp_3__sec_301 part 
because it is retained by the client and not transmitted to the server.

b) Veronique has similar problem but at work level.
External source reference like the follow:
www.europeanParliamentResolver.eu/eu/act/456/2014-10-20/main#art_45
"art_45" doesn't arrive to the resolver server.

Proposal: to use ~ for expressing fragments inside of the AKN URI.
