Semantic standards are commonly-agreed structural metadata, e.g. data models and reference data.
What is a semantic standard?

What is semantic interoperability?
Semantic interoperability is the ability of organisations to process information from external sources in a meaningful manner, such that the precise meaning of exchanged information is understood and preserved throughout exchanges between parties.

Semantic interoperability requires consensus on semantic standards for information exchange.
Semantic interoperability is fostered by the sharing and reuse of semantic standards.
Sharing and reuse of semantic standards reduces the cost of information exchange across borders and organisations.

In the context of Action 1.1 on improving semantic interoperability in European eGovernment systems (SEMIC), the ISA Programme has initiated the development of: The e-Government Core Vocabularies The DCAT Application Profile for data portals in Europe
(DCAT-AP) The Asset Description Metadata Schema (ADMS)

All semantic standards developed by the ISA Programme were developed following a consensus building process:•Involving international Working Groups of experts;• Following a formal open process and methodology – based
on the one followed by the W3C. •Foreseeing public review periods•Re-using existing standards
Core Person, Core Location, the Registered Organization Vocabulary and ADMS were initially developed by the ISA Programme and have now been taken over by W3C – discussed in the late W3C GLD.

• A common vocabulary for describing datasets hosted in data portals in Europe, based on the Data Catalogue vocabulary (DCAT).
• It enables cross-portal search for datasets. • As an application profile of DCAT, the DCAT-AP
• Defines mandatory, recommended an optional classes and properties
• Recommends a number of controlled vocabularies for assinging values to properties, e.g. Eurovoc for dcat:theme.

• A common vocabulary for representing semantic standards
• ADMS allows public administrations, businesses, standardisation bodies and academia to:• describe semantic standards in a common way so that they
can be seamlessly cross-queried and discovered by developers from a single access point;
• keep their own system for documenting and storing semantic standards and still be interoperable with others;
• improve indexing and visibility of their own standards;• link semantic standards to one another in cross-border and
cross-sector settings.• ADMS evolved into a W3C Working Group note
based on DCAT.Slide 15

Public administrations should become aware that semantic standards are an important asset for eGovernment systems development.
Public administrations should identify and document semantic standards with reuse potential for developing eGovernment systems.
Public administrations should make their semantic standards open for reuse.
Public administrations should provide their semantic standards both in human and machine-readable formats.
Conclusions
![Page 27: Semantische Standards in der Öffentlichen Verwaltung in Europa](https://reader036.vdocuments.us/reader036/viewer/2022062520/5681632b550346895dd3a5f7/html5/thumbnails/27.jpg)
Whenever possible, definitions of semantic standards should reuse existing specifications to avoid duplication of work and overlaps.
For example, we showed how the e-Government Core Vocabularies can used in many different contexts.
• They can easily be extended and integrated with other vocabularies.
• They can be adapted to your needs and context.• The can be used both in an XML and an RDF world.
