As an analyst, you seek facts, evidence, and the deeper meaning behind them.
But the questions are:
- Where to find the facts and evidence
- Which concepts are the key ones
Go to the NAPs Browser to quickly learn about:
- Countries, NAPs, and the Catalogue Records they publish.
- Publishers, their Distributions, Formats, Protocols, and Subscription Processes.
- Many Distributions include metrics such as message sizes, update intervals, number of records, and XML schema conformity.
Key concepts for data exchange are:
- DATEX II provides the class model for messages, with SituationPublication used for SRTI.
- Publishers should simplify (profile) the class model to ensure they deliver only what’s necessary.
- The profiled model should be expressed in the form of an XML Schema, serving as an agreement on the data structures to be used.
If there is no schema, ask for it—or create one if you work for the publisher.
And keep in mind that an “unprofiled SituationPublication schema” does not count.
