Building a missing item in INSPIRE: The Re3gistry

Conceptual data models Registers
• spatial objects and their properties and relationships for 34 data themes
• cross-domain harmonization
• based on a common modelling framework
• managed in a common UML repository
Harmonised vocabularies
• to overcome interoperability issues caused by free-text and/or multi-lingual content
• allow more specific terms from local vocabularies in addition to the harmonized terms
Encoding
• GML application schemas as standard encoding
• conceptual models independent of concrete encodings
• also possible to derive other encodings (e.g. based on RDF)
• provide unique and persistent identifiers for resources
• allow their consistent management and versioning
• items can be made unique and referred to unambiguously
Key pillars of data interoperability

Code lists Code lists for spatial data already
exist and should be reused in INSPIRE (wherever possible)
Key principle: Extensibility Code lists are extensible where • no agreed code lists or classifications exist in the domain • code lists or classifications in a specific domain are subject to
frequent changes (e.g. addition of values)
• code lists in a specific domain are hierarchical Extensibility gives data providers the possibility to use more specific (national or local) values

Title: Joint Research Centre Author: Grainne Mulhern Created](https://reader033.fdocuments.us/reader033/viewer/2022060516/5fc6182c02ed65633b3bb725/html5/thumbnails/4.jpg)
Code lists in the IRs 4 types of INSPIRE code lists
according to extensibility a) not extensible – only values included in IRs are allowed b) narrower extensible – values included in IRs and narrower
values are allowed c) freely extensible – values included in IRs and any other values
are allowed d) empty – any values are allowed
For code lists of types (b), (c) and (d), additional values have to be published in a register
• Technical Guidelines may include additional proposed values that will be published in the INSPIRE code list register

ARE3NA Inventories
Initial inventories • ~200 FOSS • ~1100 Member States’ relevant websites and tools • ~120 Other policy areas and ~200 of their platforms/portals
New ARE3NA survey
tinyurl.com/are3na1
• What are you using for INSPIRE implementation? • What best practices are there in aiding implementation? • What is missing and what ‘bridges’ can we build with other
sectors?
