SIS Version History

1. SIS 3

   Based on a branch of the version 2, version number 3 introduces the concept of potentially infinite spaces. Thus enabling the definition and usage of the Geodetic and Cartesian spaces.
   The introduction of that spaces put a big step towards the use of SIS not only as a middleware for indoor Ubiquitous Computing, but also for outdoor usage.
   Actually this version does not have the features and bug fixes introduced in version 2.5

2. SIS 2.5

   This version is the natural continuation of the 2.0 branch towards a more usable administration interface and API. The most important change in the API is the removal of the usage of the Handle.
   Until now the Handles were necessary to uniquely identify a space creation and a mapping creation. Now the spaces are identified by their names and mappings are identified by its given source and target contexts.
   We can't forgot to mention the increased speed in computation and the reduced memory footprint. Also, the SOAP endpoint is dead.

3. SIS 2

   The second version is a big step forward. This version includes a RESTful based Web Service using the JSON encoding.
   This version stabilize also the Web Interface for easy management and introduces the first authentication based communication.
   The big change is the support of the Web Socket standard to enable the push notification of the Matchings on a subscription.
   The SOAP web service for this version is mantained only for backward compatibility.

4. SIS 1

   The first version that enabled the creation of the space based middleware for Ambient Intelligence and Responsive Environment.
   The first version operates only on graph, grid and label spaces. All services were exposed using a SOAP based Web Service.
   Each space is a set of locations and all operations are based on locations.
