Problem: too many formats
- There are more than 20 data formats for position information today.
- This is confusing for developers and hampers development.
Realization: there need only be one
- One format could be transported in many protocols.
- It could also be included in profiles, like CC/PP.
- To make it machine readable, it should be XML.
- To integrate well with other metadata, it should be RDF.
- But if you do not want to learn XML and RDF, just treat it like a string encoding
Solution: common lowest denominator
- W3C and OpenGIS idea: A common lowest denominator - with extensions for other
- The idea comes from the XHTML modularization: Create a base module with the absolute
necessities, then add whatever you need using XML mechanisms.
