Photo metadata software/notes

by Gerald Oskoboiny

I am writing some software to help me manage my online photo collection; in particular, to make it more accessible, searchable, navigable, etc. I am using this page to keep track of related stuff (e.g., sample galleries/pages, software, metadata, documentation, my work, misc other stuff.)

Sample photo pages/galleries

To steal ideas from...


Sample metadata


Notes on related stuff I have done


See the changelog within the captivate script for info on more recent updates.


Misc other notes

Misc unresolved issues to discuss on www-rdf-interest or somewhere (review notes from chat with em first):

Very early rough notes, probably redundant now:

necessary components of photo page:

    short description (title?)
    longer description
    size (nn k)
    camera info (linked)
    link(s) to other version(s)

other optional info:

    link(s) to collection(s)
    exposure, iso, flash, metering mode, ... info

misc notes:
    - when extracting photos, add a minimal comment to the jpeg
      immediately after extraction using photopc (before adding to
      cvs), including: copyright, and uri of the image?
    - script to RDF->HTML: call it decapitate? doesn't really
      fit, but that's a cool name. (captivate/decapitate)


The proposed DIG2000 [DIG2000] file format for the (also proposed) JPEG2000
[JPEG2000] image compression algorithm contains an XML-based metadata block
with entries for people, places, events, GPS location, camera type, etc. It
allows extensions with additional entries. The draft of October 1998 doesn't
use RDF.
