Re: [CODE4LIB] Something completely different
Hi Peter, Peter Schlumpf wrote: What I had in mind for something different is this: Think of a single database of only associations between objects, and nothing more than that. If I'm understanding you correctly, what you have in mind is a triplestore. A database for storing purely relationship triples and nothing else. A triple is made up of the name of an object, the name of a type of relationship and a name of another object. A few example abstract triples might be: (The Lord of the Rings, author, J. R. R. Tolkien) (The Hobbit, sequel, The Lord of The Rings) (J. R. R. Tolkien, pet, Fido) (Fido, species, Canis lupus familiaris) (Canis lupus familiaris, commonName, Dog) etc RDF is a particular implementation of this abstract concept, where the names of both the objects and relationships are URIs. An RDF triplestore is a piece of software that stores these relationships and allows them to be queried flexibly and efficiently (in theory). It allows for an interesting extension too -- weighting those associations. Suppose we use it to create a search structure, and each time we go from one object referencing another we increment a counter for that link by one. I'm a little confused by this. What would the use case be? Are you talking about a popularity score for each relationship to weight searches with? Cheers, Alex

Re: [CODE4LIB] 2009 WorldCat Mashathon in Amsterdam
The WorldCat Mashathon is not limited to OCLC member institutions, and we certainly had non-OCLC participants at the New York event. We have many APIs, some of which are open to anyone to use and others that require a key. Again, depending on the API, for some you may need to qualify for access to receive a key. We know that we could do a better job making these distinctions apparent, which is something we'll be trying to clarify. In any case, everyone who attends will be provided with an OCLC Web Services Key (WSKey) that will be valid for the period of the event. Those who already have a key will be welcome to use their existing key as well.

Re: [CODE4LIB] 2009 WorldCat Mashathon in Amsterdam
Roy, I know there was some grumbling last time that temporary keys switched off almost the minute the conference was over. It might be more attractive if WorldCat committed to allowing mashups built during mashup events—which aren't in conflict with some rule or otherwise unattractive to OCLC, but merely show how wonderful WorldCat is—to remain functional after the event.

Re: [CODE4LIB] 2009 WorldCat Mashathon in Amsterdam
Right, but I also want to point out that those service levels only apply to the WorldCat Search API. We have many other APIs, for which those service levels don't apply.

What are you guys doing where you feel the support and tools are lacking? And what are the RDF alternatives?
