MobilityDB Release 1.1

MobilityDB 1.1 Feature Highlights

MobilityDB 1.1 is a major revision with respect to the initial version 1.0.
The most important change in version 1.1 was to extract the core functionality for temporal and spatiotemporal data management from MobilityDB into the Mobility Engine Open Source (MEOS) C library.
In this way, the same functionality provided by MobilityDB in a database environment is available in a C program to be used, for example, in a streaming environment.

To generate the MEOS library it suffices to pass the additional parameter -DMEOS=on to cmake.

Several changes were necessary with respect to MobilityDB version 1.0 to enable the above. An important one was the definition of new data types span and spanset, which provide similar functionality to the PostgreSQL data types range and multirange but can also be used in various programming environments regardless of PostgreSQL. These are template types, which means that they are containers of other types, in a similar way as lists and arrays contains values of other types. Furthermore, a new template data type set was also added. Therefore, the types timestampset, period, and periodset in version 1.0 are replaced by the types tstzset, tstzspan, and tstzspanset in version 1.1.

MobilityDB 1.1 also includes several bugfixes and performance improvements compared to 1.0.
Finally, the API of MEOS and MobilityDB was streamlined to improve usability and to facilitate the other bindings that are currently being developed.
