Better dump of all mappings, and easier to find

cygri commented 11 years ago

We already have ways of accessing all mappings through the links in the footer at http://prefix.cc/popular/all , but there are some problems with that:

A dump for backup/restore purposes would be great, that includes stuff like addition dates, upvotes and downvotes
All the undefined mappings in the big dump make it large and rather useless
There should be a proper Turtle dump, not just RDF/XML (the .file.vann one)
There should be a dump that also contains secondary (non-preferred) URIs, which is important when doing things like synchronizing with a list of mappings maintained somewhere else (like LOV)
The dumps should have .rdf and .ttl extensions rather than .vann, otherwise we confuse stupid processors that only look at the file extension
The dumps must be easier to find

Anecdotal evidence has it that people look for the dump at /all.ttl. That's not a bad place for it. The page at /popular/all could then go to /all too.

There would be some logic to /all.vann.ttl too, assuming that /all.ttl would be the pure declarations.

The RDF/XML file uses blank nodes for the prefix mappings, which makes it hard to make 5-star references back to prefix.cc.

Suggest to change what is currently provided:

bash-3.2$ rapper -i rdfxml -o turtle http://prefix.cc/popular/all.file.vann | head -25
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix vann: <http://purl.org/vocab/vann/> .

<http://prefix.cc/popular/all.file.vann>
    a foaf:Document ;
    foaf:topic [
        vann:preferredNamespacePrefix "rdf" ;
        vann:preferredNamespaceUri "http://www.w3.org/1999/02/22-rdf-syntax-ns#" ;
        a owl:Ontology
    ], [
        vann:preferredNamespacePrefix "owl" ;
        vann:preferredNamespaceUri "http://www.w3.org/2002/07/owl#" ;
        a owl:Ontology
    ],

to similar to the following to provide meaningful cool IRIs such as:

@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix vann: <http://purl.org/vocab/vann/> .

<http://prefix.cc/popular/all.file.vann>
    a foaf:Document ;
    foaf:topic <http://prefix.cc/rdf>, <http://prefix.cc/owl> .

    <http://prefix.cc/rdf>
        vann:preferredNamespacePrefix "rdf" ;
        vann:preferredNamespaceUri "http://www.w3.org/1999/02/22-rdf-syntax-ns#" ;
        a owl:Ontology .

    <http://prefix.cc/owl>
        vann:preferredNamespacePrefix "owl" ;
        vann:preferredNamespaceUri "http://www.w3.org/2002/07/owl#" ;
        a owl:Ontology .

Is there reason to hide the namespaces within a literal? The following could be nicer:

@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix prov: <http://www.w3.org/ns/prov#> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix vann: <http://purl.org/vocab/vann/> .

<http://prefix.cc/popular/all.file.vann>
    a foaf:Document ;
    foaf:topic <http://prefix.cc/rdf>, <http://prefix.cc/owl> .

    <http://prefix.cc/rdf>
        vann:preferredNamespacePrefix "rdf" ;
        prov:specializationOf <http://www.w3.org/1999/02/22-rdf-syntax-ns#> ;
        a owl:Ontology .

    <http://prefix.cc/owl>
        vann:preferredNamespacePrefix "owl" ;
        prov:specializationOf <http://www.w3.org/2002/07/owl#> ;
