| | Selbstdarstellung: | | Introduction The PictureAustralia service has been provided for use by all Australians, to discover our heritage as documented in pictures. Through a single access point, it is possible to search the distributed image collections of many significant cultural institutions, without having to know where the images are held. What is PictureAustralia? PictureAustralia is a web service based on a metadata index held at the National Library in Canberra which links to pictorial images held on the web sites of participating cultural agencies around Australia. The service has a "hybrid" architecture with a centralised search index and distributed images. Users can search the central metadata index at the National Library for their subject of interest, view image thumbnails in their results, then go to a participating agency's web site to view a larger version of the image and order a high resolution copy if needed. The user can navigate between PictureAustralia and the participating institutions' web sites using the BACK button on their web browser. What is its scope? PictureAustralia consists of links to images of all forms of Australiana. Images may be of art, abstract art, fine art, portraits, photographs of people, places and events, posters and three-dimensional art such as sculpture, scrimshaw, bark, and costume. Objects may include apparel, weapons, buildings, etc. Both black and white and full colour images are included. There are some items that will not be found in PictureAustralia. These include contemporary items that are restricted by copyright from display and textual items, unless the text forms part of an artefact. Maps and manuscripts are also not included, however photographs of maps may be. Video or audio clips are not included in the service either, but an individual frame of a video, presented as a picture, may be. An indication of the coverage of PictureAustralia can be found by reading about each image provider's contributions to the service. While a lot of metadata exists for images which have not been digitised, it won't be included for searching in PictureAustralia. However, it is available for searching on the image providers' own web sites. Some items not in scope for PictureAustralia may be found by searching within the list of 'Australian Digitisation Projects' within the Australian Libraries Gateway. How does it work? A web page about an image in the service is held on a participating agency's web site. The page will include the image itself and information that describes the image. This descriptive information is called metadata. The PictureAustralia service uses metadata in Dublin Core format. Every month the National Library gathers this metadata from each participating agency using metadata harvesting software. The metadata is stored at the Library in XML (eXtensible Markup Language) format. An index is built using this metadata which PictureAustralia users search when using the service. The software being used by the Library to gather the metadata and build the search index is MetaStar from Blue Angel Technologies. The thumbnail images in search results are retrieved from participants' web sites and are not duplicated centrally at the Library. This architecture is simple and scalable. It adds value to the pictorial collections of cultural agencies already accessible on the Internet through their amalgamation within the PictureAustralia service. The technical investment needed to join the PictureAustralia service is low especially if image collections are already web enabled. Metadata The PictureAustralia participants have chosen to use the Dublin Core metadata schema to describe the images being provided as part of this service. The Dublin Core schema has been used by many Web service providers in the cultural sector, including the Consortium for the Computer Interchange of Museum Information (CIMI). Examples of how the metadata has been applied to images in the PictureAustralia service are provided in our metadata guidelines. Australian Pictorial Thesaurus The PictureAustralia participants have endorsed the Australian Pictorial Thesaurus as the preferred thesaurus for the service. More information about the APT is available on the Australian Pictorial Thesaurus web site. New image providers The PictureAustralia service is continuing to add new image providers as more and more digitised image collections become available. New participants in the service include the National Archives of Australia and the University of Queensland Library. If you are interested in joining the PictureAustralia service, please contact us for an information kit. Trails Thematic trails have been produced with canned searches of the metadata, to highlight the images and true strengths of collections. We welcome your suggestions for new trails. History PictureAustralia began in 1998 as the ImageSearch Project with five contributors: the Australian War Memorial, the National Library of Australia, and the State Libraries of New South Wales, Tasmania and Victoria. Following the very strong initial reactions to the prototype, it was decided to expand into a new service to include more libraries, galleries, museums, and archives. The service was launched on 4 September 2000 by the Minister for Veterans' Affairs, Mr Bruce Scott, in a ceremony at the National Library of Australia and was immediately embraced by users in Australia and overseas. The National Archives of Australia and the University of Queensland Library also joined the service in time for the launch. PictureAustralia won an Australian Financial Review 2000 Australian Internet Award in the Arts category on 28 November 2000. |
