Images Model
From DigiRepWiki
In the IAP model, we have renamed the FRBR Work entity as ‘Image’ for reasons of clarity, mainly to avoid confusion between notions of Work as described traditionally in image cataloguing in the cultural sector (i.e. the physical thing) and abstract Work as described in FRBR. As noted above, image as defined in the IAP is a digital image, in line with our notion of end users searching repositories for digital images of something. Therefore our conceptual model - while still using the language of FRBR and utilizing the areas of SWAP that have applicability across the text and image domains - places the digital image at its centre.
One area where we had particular concerns with FRBR for images was in the notion of an abstract Expression layer in the model. This entity, while very useful in describing the various intellectual and artistic realisations of textual, musical and performance works, was not it seemed to us, as useful in describing images, as defined in our project scope. In FRBR the Expression points to ‘intellectual’ differences, which are not apparent to the same extent in, for instance, a format change in an image. To this end we have omitted this entity from the IAP model.
The IAP Model also makes use of the FRBR Group 3 Entities: Concept (an abstract notion or idea), Object (a material thing), Event (an action or occurrence) or Place (location), which will facilitate simple keyword searching of images. We also added to the FRBR recommendations for subject a Person Entity that we felt was necessary to express either the creator of the object depicted in the image, or a person who appears in the image. This Person information is distinct from FRBR Group 2 Entities which we have followed SWAP in consolidating as a single Agent. In the IAP Agent is typically a funder, associated institution, or the creator of an image Manifestation. Similarly the IAP follows SWAP in its use of Copy instead of FRBR Item. Here a Copy is typically a network location of a particular image Manifestation.
In natural language what this model says is that each Image can have one or more Manifestations, and each Manifestation can be made available as one or more Copies. Each Image can have one or more Subjects, Objects, Events, Places or People associated with it. Each Image can have one or more funders and affiliated institutions and each funder and affiliated institution can be associated with one or more Image. And each Manifestation can have one or more Creator, and each Creator can be associated with one or more Manifestations.
