Version 1.9-mock
This is version 1.9-mock. 1.9 because the API still have changes pending
(principally relative to the Discovery Services). “mock” because TLS
configuration is not yet available and the signatures (SigMa) are not fully
implemented.
- code cleaned and refactored
- lots of bugs fixed
- dependencies checked and trimmed
- documentation added
- Identity handling added
- code refactored
- new, better APIs
- Identity handling added
- use EPCglobal and DS events (no proxy types anymore)
- ETa-Callback modules are now available as web applications
- filtering rules: if a part of an event is not allowed, now the whole
event is deleted from the result (before only the rejectd part was)
- new temporary User web service
- new Xi module: XACML Interrogation web service (was two modules: TCP and
servlet)
- ETa and its Callback modules
- ActiveMQ
- SigMa
- certificate/signing key
- new simplified figures (sans IoTa and simplified IoTa)
- new figure for ETa modules
- show 3rd party clients
- data flows specified
- TLS and link security added
- IDs and trusted IDs added
- color adjusted for printing
- GREYC logo added
