Interesting Aspen Institute quote on messaging standards development
Draft HMIS XML 2.8 messaging API
Issues:
- We obviously wish to create the simplest standard possible ... but:
- Both DMIS-OPEN and EXML-DE both require SOAP encoding, I think, whereas REST is preferred generally as simpler and more flexible. However, the EDXL-DE docs say "This format may be used over any data transmission system, including but not limited to the SOAP HTTP binding.".
- Can RSS be used with REST to notify another agency of new information? Praveen at Red Cross brought up this idea.
- Benefits/hurdles of using EDXL-DE messaging, from David Goedecke
- Security: OASIS recommends using SOAP Web Services Security or "or some other suitable encryption scheme" to encrypt any sensitive information. What would be the REST equivalent?
