<P><FONT size=2>Hi,<BR><BR>At the University of Illinois, we have worked as a service provider on<BR>several possibilities :<BR>- asking data providers to include a URL to a thumbnails in their<BR>metadata record. The easiest way was to use a thumbnail element, used by<BR>the National Library of Australia for their Picture Australia Service.<BR>That's DC + that element<BR>- asking people to provider a richer representation of their resources,<BR>using a specific format which allows to express the different "views" of<BR>a picture (thumbnail, large ...). A similar approach can be taken with<BR>DIDL for instance or METS records. The work on this approach was part of<BR>the DLF-Aquifer project,<BR><A href="http://www.dlib.org/dlib/october06/cole/10cole.html">http://www.dlib.org/dlib/october06/cole/10cole.html</A>. The format does not<BR>really matter, but it is to propose a richer representation of resources.<BR>- a 3rd approach consisted in using the URLs found in the records and<BR>parse the pages to either recognize or create a thumbnails from the data<BR>providers Websites (with their kind permission :-)).<BR><A href="https://www.ideals.uiuc.edu/bitstream/2142/72/3/Assets.ppt.pdf">https://www.ideals.uiuc.edu/bitstream/2142/72/3/Assets.ppt.pdf</A> and a<BR>poster "An OAI-PMH Based Thumbnail Capture & Delivery Service"<BR><A href="http://oai5.web.cern.ch/oai5/images/posters/31-Cole.pdf">http://oai5.web.cern.ch/oai5/images/posters/31-Cole.pdf</A>.<BR>The following paper gives an overview of the issue<BR><A href="http://www.dlib.org/dlib/january06/foulonneau/01foulonneau.html">http://www.dlib.org/dlib/january06/foulonneau/01foulonneau.html</A><BR><BR>Most service providers do not use thumbnails because they do not deal<BR>with pictures only. But Picture Australia is definitely a good example<BR>of SP dealing with pictures and having a clear interest in showing<BR>thumbnails. Aquifer uses thumbnails, American West as well, the CIC<BR>metadata portal, the IMLS digital collections and content. All those<BR>examples have indeed agreement between data providers and service<BR>providers. I am not certain of last developments, other people could<BR>complete. I do not think there are generally accepted protocols.<BR><BR>Hope that helps.<BR><BR><BR><BR>CHARLES, Daphne a écrit :<BR>> Hi,<BR>> <BR>> I've noticed that some service providers include thumbnails in<BR>> their search results. I'd quite like to make this facility available<BR>> for any harvesters of our repository who wish to use it, but can't<BR>> find any specific references in any of the OAI DC guidelines<BR>> explaining what the XML should look like.<BR>> <BR>> Can anyone tell me if there an accepted protocol for exposing<BR>> thumbnails, or is it something agreed between individual repositories<BR>> and harvesters?<BR>> <BR>> Many thanks<BR>> <BR>> Daphne Charles<BR>> Development Team Leader (Web)<BR>> English Heritage<BR>> NMRC, Kemble Drive<BR>> Swindon SN2 2GZ<BR>> Tel 01793 414894<BR>> <BR>> <BR>> ------------------------------------------------------------------------<BR>><BR>> This e-mail (and any attachments) is confidential and may contain<BR>> personal views which are not the<BR>> views of English Heritage unless specifically stated.
