> GLOBE's data is point data collected at sites that are geo-referenced > (using the WGS-84 datum). Sites have associated metadata which depends > on the site type. Sites are associated with schools. Time series > measurements of defined data sets (air temp, humidity, etc.) are taken > at sites, and there are dependencies which are enforced between the > data. Dependencies can relate data set, time, and location, e.g. to > report measurement X at a site you must also report measurement Y taken > at the same time and measurement Z taken within an hour, at the same > site. Dependencies can be between sites - some site types require or > allow supporting data to be taken at an Atmosphere site located not more > than a certain distance from the site. The data needs to be searchable > by school(s), country(ies), lat, lon, elevation, type and amount of data > reported within specified date ranges.

It sounds to me like you need a relational database for this. Im not sure where the TDS fits in.
