This prod­uct offer­ing is com­posed of the fol­low­ing pieces:

• A cen­tral­ized data­base that con­tains def­i­n­i­tions of spec­i­fi­ca­tions (spec­i­fi­ca­tion ver­sions, coun­tries, local­i­ties sup­port­ed, code sets, objects, ele­ments, attrib­ut­es, descrip­tions of each of these and oth­er per­ti­nent information)
• A web-based appli­ca­tion that allows users to main­tain this database
• A web ser­vice that allows users and appli­ca­tions to query the data­base, extract­ing infor­ma­tion using oDa­ta query­ing conventions
• An "update" util­i­ty that uses these facil­i­ties to keep appli­ca­tions up to date by sub­scrib­ing to "feeds" from the web service

The Central Database

The fol­low­ing tables con­tain the infor­ma­tion deliv­ered by the Spec­i­fi­ca­tion Deliv­ery Ser­vice for the SIF specification.

The Maintenance Application

<doc­u­men­ta­tion to be completed>

This is the appli­ca­tion that is used to make small changes to the cen­tral spec­i­fi­ca­tion data­base. In the screen shot to the right, the "Local­i­ties" tab is select­ed, show­ing a list of cur­rent­ly sup­port­ed SIF local code sets, Extend­ed Ele­ments, etc.. Oth­er tabs include :  Spec Enti­ties — this is the bulk of the infor­ma­tion from the spec­i­fi­ca­tion, includ­ing the def­i­n­i­tion of the ele­ments and attrib­ut­es for all of the SIF objects Code Val­ues — this con­tains def­i­n­i­tions (and full descrip­tions) for all code val­ues in all ver­sions of the SIF spec­i­fi­ca­tions plus those used in the sup­port­ed localities Extend­ed Ele­ments — these are known Extend­ed Ele­ments for all objects that have been sent to this reg­istry for elec­tron­ic distribution Meta­da­ta — this con­tains infor­ma­tion that is used for auto­mat­ic updat­ing of tables (inter­nal use) Man­age Users — used for site administration Man­age Roles — used for site administration
