Re: My Web Site Description in OWL

Hi Phil,

thank you very much for your answer and the suggestions on how to use 
POWDER for that.

I investigated OAI-ORE with respect to that and it partially does what I 
would like to do. Actually I worked on a model which is able to 
represent information about different resources and authors of them (the 
RICO model, see [1] for a presentation and [2] for a preliminary paper 
about it).

This is definitely of use for another application I am currently 
implementing. Actually your example can be immediately be implementable 
with Flickr for example which is nice (Flickr stores the images of each 
user in separate directories and provides URLs by which the contributor 
of an image can be identified) If I store images in a similar way the 
solution you suggest is of help for me. thanks!

Best regards,

Tobias
