[Mobilitydb-dev] [EXTERNAL] Re: Joint release candidate 1.1 of MobilityDB, MEOS, and PyMEOS

[Wendell Turner]

Yes, this is good news.  Glad to hear of the release.

Is the database format for v1.1.0rc1 the same as for v1.1.0-alpha?

Regards,
Wendell

You don't often get email from mobilitydb-dev at lists.osgeo.org. Learn why this is important<https://aka.ms/LearnAboutSenderIdentification>
Congratulations to the whole team. That's excellent news.

By the way, are you planning a Mobility DB presence at FOSS4G Europe? (It's the week after MDM2024.)

Regards,
Anita

The MobilityDB team is proud to announce that the joint release candidate 1.1 of MobilityDB, MEOS, and PyMEOS
https://github.com/MobilityDB/MobilityDB/releases/tag/v1.1.0rc1
https://github.com/MobilityDB/PyMEOS/releases/tag/pymeos-1.1.3rc1
is now available for download. This release contains all the features that will be available in the final release.

In the spirit of the open source PostgreSQL community, we strongly encourage you to test the new features of MobilityDB 1.1 on your systems to help us eliminate possible issues that may exist. We encourage you to find ways to run your typical application workloads against this candidate release. The final 1.1 release is planned in a few weeks after we have received user's feedback regarding the current candidate release.

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.
https://libmeos.org/
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.

The MEOS library for mobility management provides similar functionality as the Geometry Engine Open Source (GEOS) C/C++ library for computational geometry. In addition, bindings for the MEOS library in other programming languages are available, in particular for Java with JMEOS, for C# with MEOS.NET<http://meos.net/> and for SparkSQL.
https://github.com/MobilityDB/JMEOS
https://github.com/MobilityDB/MEOS.NET
https://github.com/MobilityDB/MobilitySpark
Drivers for other programming languages and environments such as Javascript, Rust, and DuckDB are being developed.

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. Finally, the API of MEOS and MobilityDB was streamlined to improve usability and to facilitate the other bindings that are currently being developed.
