*Haystack -- a semantic web browser
- http://haystack.lcs.mit.edu/publications.html

** Has presentation 'recommendations', like CSS

** Interesting idea of content type -> service

  "semantic matching of resources to services that can consume them
  can be done by the client and exposed in the form of menus."

** Abstraction of the store, to hide retrieval of resources

***Caches remote RDF
***Supports 'events' -- callbacks for when a particular triple comes up

**Federated RDF stores

**Collections handling

**Closures

***Users asked for missing arguments to operations

***Can save an unfinished closure as an operation

***Closure views also act as a sort of UI continuations

Haystack and Adenine would be interesting to recreate as an embedding in something
like SmallTalk or Scheme.

Interestingly reflective; if you could go further and represent the
outer language in the database ..
