I will be posting about it later today but wanted to draw your attention to: Hacking Chess with the MongoDB Pipeline http://www.snailinaturtleneck.com/blog/2012/01/26/hacking-chess-with-the-mongodb-pipeline/ By Kristina Chodorow. Kristina uses the new aggregation facilities of MongoDB to analyze chess games. Aggregation is based upon uniform identifiers (chess pieces/moves) but the important point is that the analysis she presents isn't possible in the absence of aggregation (actual or simply keeping a mental tally). I was thinking the what analysis is/is not possible in the absence of aggregation might be a fruitful topic of discussion. Hope everyone is having a great week!

Message-ID: <4F4EC49F.9050105@durusau.net> Greetings! Sorry for the long silence. I wrote a post today that may be of interest to the members of SC 34: Graph Databases: Information Silo Busters http://tm.durusau.net/?p=22342 Some of the more advanced graph database products, in this case InfiniteGraph 2.1, are starting to talk about persisting relationships across datastores. It occured to me that persisting those relationships/mappings in an interchangeable fashion, would be something very much in the vein of topic map work. The usual suspects of data types, ranges, etc., purely declarative, database/table/other structure names/locations, etc. Would that be: #1 of interest #2 something you would like to contribute time/resources to #3 something you already have etc.? Hope everyone is having a great week!
