The document defines a metadata profile - the Plan4all Metadata Profile - for cataloguing spatial planning activities across Europe. The profile is designed to provide metadata for spatial plans, datasets that are part of digital spatial plans, and spatial services providing access to digital spatial plans. The profile is compliant with ISO 19115, INSPIRE, and other relevant standards. It includes elements for describing spatial plans, datasets, and services, and guidelines for implementation including XML schemas, multilinguality, and linking between different metadata records.
