[open-bibliography] Linked Open BNB preview now available

Thu Jul 21 09:40:34 UTC 2011

Hi William,

Many thanks for your kind words and suggestions. Some comments:

1. On having pointers back from docs for the authors to their books
We've been discussing materialising more inverse relationships; this is on our list of things to do. It may not happen immediately, but we do intend to update the BNB dataset, both in terms of its currency but also in terms of adding features to the RDF.

2. Adding metadata on the doc URIs about metadata 
e.g who created, published the RDF, when, license information, etc. Again this is on our list of things to do.

Could you please expand on the usefulness of including the timestamp from the 005? 

First because by doing so, you're bringing back the MARC bibliographic record into the data model. We had long discussions about that and in the end, decided not to model the MARC bib record. The only point in doing that would have been to be able to attach metadata about that MARC record, and we understood that this was of limited interest to the Linked Data community. Your suggestion seems to suggest otherwise. 

Secondly, the date contained in the 005 is the date of last transaction of the record. It could just be correcting some admin data, which we don't include in the RDF output in any case. You just don't know which bit of the record has been updated. So I don't think the 005 can tell you much reliably about the "age of the record".

3. the VoID description is in draft form, we just didn't publish it with the preview subset.

Cheers

Corine

Hello Corine, hope you are enjoying your well deserved vacation!  This
is brilliant work, very much better than the previous RDF version,
URIs everywhere, beautiful!

A couple of tiny suggestions, first would be on the documents for the
authors, to have pointers back to their books, this will help with
follow-your-nose navigation. 

The second, very minor, would be to stuff
the timestamp from the MARC 005 somewhere so the age of the record can
be judged, and similarly for the creation of the RDF.

I would tend to model this last as something like,

<http://bnb.data.bl.uk/doc/resource/014938424> opmv:wasGeneratedBy [
    a opmv:Process;
    opmv:used [ ## maybe give this its own URI, but don't block on that
        a bibliographic:MarcRecord;
        dct:modified "YYYY-MM-DDTHH:MM:SSZ" ## from 005
    ];
    opmv:wasPerformedAt [ 
        a time:Instant;
        time:inXSDDateTime "YYYY-MM-DDTHH:MM:SSZ"
    ].

This also gives you a place to put any other information that may be
useful or interesting about the process for generating the RDF, such
as software used, person responsible for doing it, etc.. (notice it 
is on the /doc/ not the /id/). There are other ways to represent this
kind of information, the above is just my preference.

Icing on the cake would be to make a void:Dataset description for the
whole thing, containing information such as is on the information page
and then (possibly) link to that from the records and people tying it
all together into a neat package.

But on the whole very well done!

Cheers,
-w
