1) My repository does not aim for accessibility and/or usability of its contents beyond the short term (say 3 years)
Part of our work to examine the feasibility of approaches to improve the consistency with which repositories share descriptions of repository policies (e.g. on IPR) - this idea -, metadata and the materials themselves.
Examples include content management systems, virtual research environments, CRIS etc
2) My repository aims for accessibility and/or usability of its contents for the medium term (say 4 to 10 years)
Repositories have a function as a source of the latest R&D knowledge, which should be exposed rather than kept hidden from users. Their content should be made available to wider audiences using current awareness tools such as RSS feeds. RSS also could help to increase the interest of authors as well, in order to boost the deposit rate.
Again, the Andy Powell idea. This one, I think, more about sharing, embedding, mashups. Think Flickr. Think sneep.
Inconsistency is a fact of life, and any repository instance or system that wants to avoid bottlenecks is going to have to accept items that have inconsistent metadata (and possibly inconsistent formats and policies, though consistency in those areas may be easier or more important to enforce). That doesn't mean you have to settle for it, though. It's possible to take a progressive approach, where messy metadata comes ...more »
3) My repository aims for accessibility and/or usability of its contents for the long term (say greater than 10 years).
Most early Institutional Repositories were research repositories. Some are purely repositories housing digital objects as in "Repositories are "collections of digital objects"". However, since one of the primary aims is to showcase the intellectual assets of the institutions (as compared to providing Open Access to peer reviewed journal articles) another model was 'hybrid'. The use as a bibliography (suggested both by ...more »
Part of our work to examine the feasibility of approaches to improve the consistency with which repositories share the materials they hold (this idea), the metadata and descriptions of repository policies
Far from becoming irrelevant, metadata for repository items will
become more important but it will increasingly be created and assigned
remotely. This will be by automated procedures such as indexing and
text analysis and also by users and readers, through the use of
tagging mechanisms. These developments will have implications for
consistency between repositories and between items.
Managing data can be a big problem. Any data that might, for example, become supplementary data in an article, needs curating. Help the user by providing facilities to capture and hold intermediate versions of the data, ad the final public version.
