Organisation: 
Geoland 2 SDI task
Acronym: 
g2SDI
Details
Mission and Objectives: 
Geoland2 intends to constitute a major step forward in the implementation of the GMES Land Monitoring Core Service (LMCS). The three components (Regional, Continental, and Global) of the LMCS are addressed. The architecture of geoland2 is made out of two different geo-information service layers, the Core Mapping Services (CMS) and the Core Information Services (CIS). These form ten service groupings; all together are responsible for the definition, algorithmic evolution and pre-operational generation of some 70 different products (geospatial data set series and algorithmic tools). The Spatial Data Infrastructure (SDI) Task in the project aims to set up a pre-operational service for the discovery, viewing, access, delivery and the support of all products generated in the geoland2 project by the Core Services. For this the SDI task considers INSPIRE as the baseline. The main actors are the CMS/CIS service providers and users (both human users and applications, e.g. GMES downstream services) who consume geoland2 services. As described above a consumer of services will often be a provider of services to other users. This applies both internally and externally of the LMCS. The SDI establishes first of all the mechanisms for discovery of all dataset series and services provided by geoland2 by means of a centralised point of access to ‘dataset series and services’ catalogue. The SDI provides also distributed access to dataset catalogues residing at the various CMS or CIS service providers. These services are accessible via the CSW ISO Application profile protocol (OGC 07-045) and more in particular its SOAP binding. A BPEL-compliant orchestration engine is used for implementing the distributed catalogue. Metadata is provided in ISO 19139:2007 format. A common metadata profile is agreed amongst all service providers in the project and is promoted for wide adoption by other land monitoring initiatives. The SDI is hence the “single access point” provided by geoland2 allowing clients to discover metadata of any of the connected production centres, without necessarily hosting the metadata at one central place. The SDI offers online data-access client applications which allow service providers to configure distributed view services as well as download services. The distributed services connected via SDI should be compliant to the INSPIRE draft Implementing Rules for view services or download services. An ordering client application is available to connect to ordering services residing at the CMS/CIS service providers. The standardised ordering interface is compliant with OGC 06-141, which allows the service to be accessible to the users of the portal and to other external clients via the SDI. The authentication interface exposed by the SDI is compliant with OGC 07-118. It uses SOAP over HTTPS to provide a user name and password and to return a signed SAML token and user assertions as defined in the specification. The authentication interface is expected to be compliant with ws-trust. Each production centre may implement user access using a local Policy Enforcement Point (PEP) and associated Policy Store or delegate this access control to the PEP of the SDI. Policies are expressed in XACML.

    Specific Expertise
    Previous Experience relevant for INSPIRE development
    Note about above data themes: the SDI tasks does NOT produce or use data. The SDI takes care of the dissemination of it. So we have established a common geoland2 metadata profile, which covers different themes.
