Re: vocabulary versioning and preservation

Herbert,

This is very useful and your second paragraph on preservation causes me to
ask the question if we should not include records retention among Best
Practices.  I think the public scandal of Hillary Clinton's email server
illustrates that many organizations do not have comprehensive records
retention policies governing Open Data, email, and other information.

Your note addresses archiving published data, but I also ask how an
organization can assume best practices in publication if they do not yet
have policies to retain that which is not yet decided to be published?


Best Regards,

Steve

Hi all,

I had the time to have a closer look at the "data on the Web Best
Practices" document. I have further Memento-related comments for two
other sections of the document:

(1) vocabulary versioning

The Memento-related comments I made about Data Versioning apply
equally to Vocabulary Versioning. All approaches described in
<http://mementoweb.org/guide/howto/> apply to data and vocabulary. As
a matter of fact, when implementing Memento protocol support for both
data and vocabularies used in data, temporal versions of the data can
automatically be aligned with the temporally correct version of the
used vocabulary.

(2) preservation

The Memento protocol can play a significant role in the realm of
access to preserved data, as is exemplified by its broad adoption by
web archives and the demonstration implementation of the DBpedia
archive. But it also plays a role in making preserved/captured
resources recognizable via the Memento-Datetime header (expresses
datetime of capture/preservation) and the HTTP Link header that
carries an "original" link that connects a preserved/captured resource
with the URI where it originally resided.

Cheers
