From the website:
DSPL is the Dataset Publishing Language, a representation language for the data and metadata of datasets. Datasets described in this format can be processed by Google and visualized in the Google Public Data Explorer.
- Use existing data: Just add an XML metadata file to your existing CSV data files
- Powerful visualizations: Unleash the full capabilities of the Google Public Data Explorer, including the animated bar chart, motion chart, and map visualization
- Linkable concepts: Link to concepts in other datasets or create your own that others can use
- Multi-language: Create datasets with metadata in any combination of languages
- Geo-enabled: Make your data mappable by adding latitude and longitude data to your concept definitions. For even easier mapping, link to Google’s canonical geographic concepts.
- Fully open: Freely use the DSPL format in your own applications
For the details:
A couple quick observations:
Geared towards data that can be captured in csv files, which are considerable and interesting data sets, but only a slice of all data.
Did not appear on a quick scan of the tutorial or developer guide to provide a way to specify properties for topics.
Did not appear to provide a way to specify when (or why) topic could be merged with one another.
Plus marks for enabling navigation by topics, but that is like complimenting a nautical map for having the compass directions isn’t it?
I think this could be a very good tool for investigating data or even showing, but if you had a topic map, sort of illustrations to clients.
Moving up in the stack, both virtual as well as actual, of reading materials on my desk.
