AustLit
Fortnightly Report - Week 52 and 53, 17 May 2002
What I've done
- Very little progress on implementing the scoped search or
converting the works with awards-as-subjects and dates to use
scoped awards as subjects. Some searching algorithms have been designed
and tested, and they seem to work, but I haven't yet added them
to the search subsystem.
- A great deal of time has been spent in email and meetings discussing
issues arising from our implementation of the FRBR model, especially:
- use of the first-known-date and the override date, and the use
of dates on creation, realisation and embodiment events
- when the changes to an expression are so great that they trigger
definition of a new (but related) work
- pseuds/writing names, and especially whether attributes transfer from
the "real" person to the pseud (and vica-versa), and does a search
for works by the pseud return works by the "real" person (and vica versa).
I think some of the discussions are arising from the consideration of
the scope constraints of AustLit, which doesn't seek to be a universal
catalogue of everything, but has a strong focus on Australian
Literature. Consequently, music, songs, illustrations, performances
and other non-literary expressions, although perfectly representable
within our FRBR model, are not "core", and when non-core attributes
(such as dates) effect the literary side of things, well, it gets
ugly. For example, if a poem existed/was published as a "song" (say,
in sheet music) before it was published as a poem, should that
date be taken as the first-known-date of the poem? If a poem is
slightly illustrated, then it is probably just a new expression of the poem,
but at some point, the illustrations are so extensive that is morphs into
a new work, maybe a "picture book".
I suppose creating a specialised set or view of the world will always
bring up these problems, especially if the broader goal is for
interoperability with broader systems (such as a national/international
catalogues which may one day be based on FRBR): it would probably not
be good if we treated something as an expression, yet general cataloguers
treated the same thing as a separate work...
- Produced two papers for the Ausweb02 conference
in July:
-
Schema Driven User Interface Generation -
Building Advanced Web-based Interfaces using presentation schema, XML,
the DOM and background HTTP connections
- Taking RDF and Topic Maps seriously - what happens when
you drink the Kool Aid.
AustLit are paying for my registration and I'm paying for travel and accomodation.
- Marie-Louise has prepared a fantastic paper for the IFLA conference
later in the year: Report on the successful AustLit: Australian Literature
Gateway implementation of the FRBR and INDECS event models, and
implications for other FRBR implementations.
- Changed all role=author/creator to role=illustrator on works of form "interview"
where there was just one author or creator.
- Changed all role=sponser to role=publisher on works of type "publisher series".
- Added new form type: "index".
- Added 'publication year' as a new search criteria on advanced search
following a request from Kerry, but I'm not sure this is what is wanted
as it only searches on manifestation year, and doesn't include source
year...
- Changed the "First Known Date" calculation to ignore work creation date
- A few changes to programs, stylesheets and other formatting following maintainer and
user feedback (suppressed language at the expression level of works being shown as a source);
sundry template changes (maint note now defaults on new agent/work, publisher removed
from periodical); changed author-creation-date rendering as suggested by Joan;
bundled up manual notetab files and DTD's for Carol;
)
- The system was stable.
However, this morning we discovered that ADFA ITSC had implemented a new
firewall arrangement, and that the public IP address of the AustLit server
had been changed!! Although the DNS name remains the same (www.austlit.edu.au),
DNS changes take time to propogate through the network, and hence many
users could not connect to AustLit as the server name was been mapped into
the old IP address. To compound matters, there was a problem with the
firewall translating the public IP address of the AustLit server into
the "private" IP address, which prevented access from users even with
the new DNS mapping, but this was quickly fixed by ITSC. So, a frustrating
morning, and apologies to our users for the unavailability of AustLit for
several hours.
I've had many reports from UQ and Flinders over the last fortnight of problems
accessing AustLit, or very slow response. However, the server has been
lightly loaded, and I cannot reproduce them. Often, one remote site
is having difficulties, and others are working fine, so I suspect that
most of these issues are related to wide-area-network problems, which
we also experience here quite frequently trying to get to outside sites.
Next Fortnight
- Conversion of award-as-subject with years to use relationship scopes.
Concurrently change search algorithms to use the scope for year searches
associated with awards.
- Think about preparing AusWeb02 presentations.
Next few months
- Move awards to be event-based rather than work-based.
- Refining NBD Holdings searches.
- Review all subset definitions for efficacy.
- Import/export in MARC and DC formats.
- SDI facility.
- Combining searches
- System Documentation
