A new edition of the Land Administration Domain Model (LADM) is under further development in ISO/TC 211 on Geographic Information. The Committee is developing this new edition of the LADM – as multipart – working titles are as follows:

Part 1 – Fundamentals
Part 2 – Land Registration
Part 3 – Marine Space Georegulation
Part 4 – Valuation Information
Part 5 – Spatial Plan Information
Part 6 – Implementations

The decision to publish LADM Edition II as multipart had as a consequence that a New Work Item Proposal (NWIP) and a Working Draft (WD) have to be formulated for each Part. In 2020, the NWIP/WD have been submitted to ISO/TC 211 for Part 1 by Standards Australia (SA) with input from the author team on behalf of the FIG. The result of the voting was positive.
Comments have been submitted, which will be processed and used in the next stage of the standard: the Committee Draft. It is planned that FIG will submit the NWIP for Part 2 before summer 2021. And it is expected that the same will happen this year for Parts 4 and 5. Those submissions are expected to be in close cooperation with other international professional organisations (i.e. IHO, RICS, OGC, etc.).

The editors of the LADM Edition II have the intention to publish papers on the developments on a regular basis. It is important to remember that these are ongoing developments with undergoing changes and may change at the time of the voting rounds. However, the main concepts and development will be communicated to the reader. This paper will focus on the developments and related discussions for Part 1 of the LADM Edition II. This part provides the definitions, a general overview of the model in its individual packages and a more detailed overview of the LA_Source (with a backwards compatible integrated administrative and spatial source added) and VersionedObject (now with standardized support for the bi-temporal model with intervals for both system and real world times) classes.
