Short for Data Space Transfer Protocol, a protocol used to index and categorize data using a XML -based catalogue.

Data, no matter how it is stored (e.g. file, type of file, database, or distributed database ), has corresponding XML files, which contain UCK (Universal Correlation Key) tags that act as identification keys.

Data is retrieved when a user connects to DSTP servers with a DSTP client and asks for specific information. Data is found and retrieved based on the labels contained in the UCK tags.
