[drf:1966] Fwd: Notice of cessation of PADI gateway and padiforum-l



皆様
たびたび済みません。
最初の土屋先生の問題提起(人力によるサブジェクト・ゲートウェイの維持可能 
性)について、もう一つ象徴的なニュースがあります。
オーストラリア国立図書館が維持してきたデジタル保存に関する情報源へのゲー 
トウェイの閉鎖です。
やはり図書館スタッフが人力で維持していくのは無理という判断のようですね。

Apologies for cross posting

The PADI subject gateway http://www.nla.gov.au/padi/
<http://www.nla.gov.au/padi/>  and associated list padiforum-l
http://listserver.nla.gov.au/wws/info/padiforum-l were initiated as a
service to the digital preservation community and have been maintained
by the National Library of Australia since 1997 in order to collocate
selected information on digital preservation. For background information
see “About PADI”, http://www.nla.gov.au/padi/about.html .

Currently the gateway includes links to a little over 3000 resources
organised by over 60 topics which can be browsed using the topic listing
http://www.nla.gov.au/padi/topics/thesaurus.html .

As is to be expected with any portal to Web based documents maintenance
of web links becomes progressively more demanding over time.  Websites
are redesigned, migrated to new platforms, URL’s are changed, projects
and their websites cease, so called persistent identifiers are not, and
even when web documents or pages are archived in a web archive,
questions arise as to which version of an archived page to link to
(which date or even which archive as copies may be held in multiple web
archives with different levels of completeness).  The current structure
of PADI requires the Library to commit around 0.5 of a fulltime staff
member to locate, describe and enter links to new information sources
and to maintain links to existing resources.  Although originally
conceived as a cooperative contribution model, increasingly the burden
of adding material to PADI has fallen to the NLA as input from elsewhere
has almost ceased.

The information-seeking and information-providing mechanisms of a
community also change over time.  After reviewing the gateway service
the Library has concluded that the existing website, database and list
no longer meet the current needs and that the Library’s resources are
best invested elsewhere.  While there may be more efficient ways of
building a service like PADI today, using Web 2.0 tools, the Library is
unable to make the investment in converting the existing service.

Reluctantly – because we still find PADI useful ourselves – we believe
we cannot sustain PADI, and have decided to cease maintaining it.

A copy of the website has been archived in PANDORA
<http://pandora.nla.gov.au/tep/10691>, Australia’s  Web Archive.  The
existing live website will remain available until the end of 2010;
however no new resources have been added since the start of July 2010
and the existing links will not be actively managed. The archives of the
padiforum-l list will continue to be available , however no new postings
will be accepted from 30 September 2010.

Thank you to all who have been interested in and worked on PADI over the
past fourteen years.

Regards

Maxine Davis
