ELF Data Model
The ELF data model and the application schemas strongly build upon the INSPIRE specifications and constitute a scale-independent data model.
It should therefore adhere to the requirements and recommendations in the INSPIRE Generic Conceptual Model (GCM). The ELF modelling guidelines are formed in such a way that an existing INSPIRE implementation by default is conformant to an ELF specifications for the themes that are in the remit of the ELF data specifications. The impact of such a precondition is that all ELF additions have to be optional (not even voidable), and that there should be no constraints on INSPIRE that affects the INSPIRE GML application schema.
The ELF UML data model is defined as an Enterprise Architect (EA) project. It contains the ELF application schemas with the definition of feature types, data types and code lists.
The ELF GML application schemas version 1.0 (final versions for the project) extend the INSPIRE GML application schemas version 4.0, published in 2015. The ELF default encoding table provides an overview of the recommended GML application schemas and the relation between ELF and INSPIRE.
