making links

• we constantly improve the web

• we constantly improve how we build the web

• we still have a ways to go

a fragile web

• just using search link patterns is brittle

• wikipedia, google, and bing do better than we do at connecting resources across institutions

• we have more content that isn’t easy to find

• how can we improve this?

proxy resource URIs• commit to a stable resource

URI for each concept/name for each institution

• use that URI to show your own links to your own holdings

• use that URI to find external links to your holdings

• use that URI to show external links to related holdings

proxy resource URIs

• a “home page” for each concept at each of our sites

• threads together diverse content at each of our sites

• makes it easier to weave threads of content from diverse sites together

caching concepts

• concept resource URIs should indicate “same as” status with major concept sources

• these URIs should also publish local caches of the “main” concept source data

caching concepts

•supports efficient local processing

•adds stability when remote sites go down

•we often do this in our ILS already

strengthening meaning

• can apply to registries as well as catalogs, repositories, exhibit sites, reference resources

• makes concepts and their meaning a more prominent part of our own sites and the web we are building as a whole

thank you!
