Features that are no longer supported, since I switched from a palm PDA to a sidekick:

• export palm datebook in RDF

  core code is tellRecord in pdkb.pl schema is available

  TODO: private stuff as rules, rather than as XSLT code. (use Sandro's XSB stuff?)

  ISSUE: timezones. I think I've got an idea: TimBL suggested that private, category, etc. should be local properties. pd:start_time and pd:end_time likewise. Treat time as a local phenomenon. Have rules that say "today, the gizmo is in UTC-0500"

  ISSUE: for fields like private, a boolean-valued property seems straightforward, but it's conventional to use Classes to represent one-place predicates. Problem: we don't have a concise way to set such a flag to "false". We can say { :record rdf:type [ daml:complimentOf :Private ] } but that's a mouthful.

  ISSUE: what should be the URI of a record? base it on the palm record-id? or should the record ID be a property? (use the serial number of the device?) In other words, what's the subject of all these properties? is it the (mutable) record in the palmpilot? is it the value stored there? is it the event represented by the record? This issue hasn't come up in the code yet, but it has come up in noodling on how to do synchronization.

  IDEA: put enough information in this schema to derive an SQL schema from it. Then derive that SQL schema, ala rdf2dot

• format RDF datebook in HTML

  DONE: driven by a template ala addressing schemes,

  see datebook2html.xsl; lots of expedient hacks in here. I just (19Apr) added grouping by days to the schedule of events.

  TODO: exploit alarms in the display; differentiate things I plan to do (vs. things I know about) using alarm info? Think about rules for computing alarm info.

  Now that gerald gave me the algorithm to convert YYYY-MM-DD to day_of_week, I should be able to generate a weekly view of any particular week.

• serve DatebookDB.pdb as RDF via HTTP:

  core code is serve_datebook in pdkb.pl

  • server home is an HTML form that allows you to select a range of dates

    @@TODO?: support PUTting records via forms? (this can be a layered service on top, and I might want to keep it that way.)

  • you can GET records that overlap a range of dates, ala export above
  • you can GET the whole datebook
  • you can POST new records to the datebook
  • you can GET an individual record
  • coming soon: PUT (edit) an individual record

Installation/Requirements

Back up your data. This is alphaware. It's designed to only read your data, but who knows... no warranties and all that.

Then you'll need...

a copy of your DatebookDB.pdb

I use coldsync; you can use pilot-xfer (part of pilot-link) or whatever

an XSLT processor

I use XT by James Clark (see XSLT.mak@@)

Palm::Datebook.pm

I've used p5-Palm-1.2.2.tar.gz from coldsync, but you can get it via CPAN as p5-palm (I think@@) or as the libpalm-perl debian package

python

recent notation3.py versions require unicode support; so python 1.6.x or pythong 2.x (specifically: @@debian packages I use; windows stuff timbl uses)

I removed the dependency on cwm.py, notation3.py and xml2rdf.py from TimBL's semantic web area for play by making the two alarm properties share a subject with the rest.

Testing
