Such control may be necessary to ensure profits, or to respect agreements with other providers in the value chain, or to respect privacy rights, or to reduce risks to information, lives, real property or national security, or perhaps for other reasons. This article looks at the role of standards in securing geospatial information.

From here to eternity: an experiment applying the e-framework infrastructure for education and research and the SUMO ontology to standards-based geospatial Web services / K. Stock in International Journal of Spatial Data Infrastructures Research, vol 5 (Year 2010)

These standards often use description logic ontologies (for example, OWL-S) and are intended to be machine-readable. They have been applied to geospatial web services to describe the functions that those services perform in a way that can be automatically interpreted by systems. By contrast, little effort has gone into the development of human readable descriptions of resources in a services oriented architecture, other than using unstructured natural language. e-Framework is an infrastructure for the higher education environment that provides a typology of human-readable artefacts that can be used to describe resources, and provides an internal structure for those artefacts. e-Framework has thus far not been used with geospatial information even though geospatial information has a number of important roles in education and research, and has a well-organised community of users and creators. This paper applies the e-Framework infrastructure to OGC web services, and also recommends the refinement of e-Framework with the use of the SUMO Upper Level Ontology to define Service Genres, the most abstract level of artefacts in e-Framework. It then illustrates the ways in which the Open Geospatial Consortium standards and specifications may be described in e- Framework. The work evaluates SUMO for e-Framework purposes, finding that its use for Service Genres is possible and offers a number of gains. It also evaluates e-Framework from a geospatial perspective, and shows that e-Framework's constraints on resource descriptions do not suit the large and complex nature of geospatial web services.

A semantic registry using a feature type catalogue instead of ontologies to support spatial data infrastructures / K. Stock in International journal of geographical information science IJGIS, vol 24 n°1-2 (january 2010)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 24 n°1-2 (january 2010) . - pp 231 - 252 Titre : A semantic registry using a feature type catalogue instead of ontologies to support spatial data infrastructures Type de document : Article/Communication Auteurs : K. Stock, Auteur ; R. Atkinson, Auteur ; C. Higgins, Auteur ; et al., Auteur Année de publication : 2010 Article en page(s) : pp 231 - 252 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Infrastructure de données [Termes IGN] Catalog Service Web [Termes IGN] information sémantique [Termes IGN] infrastructure urbaine de données localisées [Termes IGN] ontologie [Termes IGN] registre de métadonnées Résumé : (Auteur) The use of a semantically rich registry containing a Feature Type Catalogue (FTC) to represent the semantics of geographic feature types including operations, attributes and relationships between feature types is required to realise the benefits of Spatial Data Infrastructures (SDIs). Specifically, such information provides a more complete representation of the semantics of the concepts used in the SDI, and enables advanced navigation, discovery and utilisation of discovered resources. The presented approach creates an FTC implementation in which attributes, associations and operations for a given feature type are encapsulated within the FTC, and these conceptual representations are separated from the implementation aspects of the web services that may realise the operations in the FTC. This differs from previous approaches that combine the implementation and conceptual aspects of behaviour in a web service ontology, but separate the behavioural aspects from the static aspects of the semantics of the concept or feature type. These principles are demonstrated by the implementation of such a registry using open standards. The ebXML Registry Information Model (ebRIM) was used to incorporate the FTC described in ISO 19110 by extending the Open Geospatial Consortium ebRIM Profile for the Web Catalogue Service (CSW) and adding a number of stored queries to allow the FTC component of the standards-compliant registry to be interrogated. The registry was populated with feature types from the marine domain, incorporating objects that conform to both the object and field views of the world. The implemented registry demonstrates the benefits of inheritance of feature type operations, attributes and associations, the ability to navigate around the FTC and the advantages of separating the conceptual from the implementation aspects of the FTC. Further work is required to formalise the model and include axioms to allow enhanced semantic expressiveness and the development of reasoning capabilities.
