Item type:Publication, CERIF-CRIS Reference Implementation (CC-REFIM) and CERIF compatibility testing system: Project Charter(euroCRIS, 2015-10-02); ; ; A technical description is provided of the CERIF-CRIS Reference Implementation (CC-REFIM) project internally developed by euroCRIS. This project aims to provide a reference system able to reliably check and confirm CERIF compatibility of (a) CERIFCRIS software platforms (e.g. PURE, CONVERIS, Symplectic Elements, Research in View, etc.) and (b) individual operational CERIF-CRIS systems currently in production, for example institutional,national or international CRIS (e.g. OpenAIREplus, EuroRIs-Net+); for example, candidates for checking with Scenario (b) are all systems that are registered on the euroCRIS Directory of Research Information Systems (DRIS).. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, CERIF REST API Specification v1.0(euroCRIS, 2015-08-31); Specification of a standard API that enables 3rd party software programs to access and reuse Research Information maintained in Current Research Information Systems (CRIS). The primary objectives of the CERIF API are a) to facilitate the interoperability of CRIS systems and their integration with other information systems and b) to enable the development of applications, services and components that can access and reuse information across different CRIS systems in a standard, unified way. The CERIF API is mainly addressed to a) organizations and individuals (e.g. software developers, product managers, CRIS managers) involved in the implementation of CRIS software platforms, individual CRIS systems and related services and b) organizations and individuals (e.g. software developers, product managers) involved in the development of software applications, services and components that can benefit from retrieving and reusing the information stored in CRIS systems. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, OpenAIRE Guidelines for CRIS Interoperation based on CERIF-XML(euroCRIS, 2013-05-13); ; The presentation describes the initiative taken by the OpenAIRE European project for enabling CERIF-based CRIS systems to become additional data providers for this content aggregation. The OpenAIRE Guidelines for CRIS Systems will be based on a CERIF-XML exchange format developed for the purpose matching the CERIF-compliant OpenAIRE data model with the CERIF-based CRIS metadata standards. Besides widening the OpenAIRE system coverage beyond Open Access repositories, this will also allow for additional digital objects to be collected such as datasets held in CRIS systems. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Providing an application-specific interface over a CERIF back-end: challenges and solutions(euroCRIS, 2014-05-13); This paper presents a case of presenting information modelled in CERIF through an application-specific programming interface which does not require CERIF expertise by the developers. The CERIF data model is semantically rich and can be used for detailed description of entities of scientific / research activity. A sophisticated application interface is required to exploit the full range of CERIF capabilities. On the other hand, it is obvious that data about scientific-research entities are utilised by users and software developers with various level of familiarity with the CERIF model. Because of the diversity of CRIS systems’ users’ knowledge of CERIF, in certain cases it is useful to create an additional application interface with elements of some simple model which can be easily understood and used by users with low level or without any knowledge of CERIF. The article presents the design and implementation of a wrapper that enables bidirectional conversion of entered data using a simple model application interface to a CERIF back-end and the use of the wrapper in the ENGAGE project as part of an open infrastructure for Public Sector Information. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, A multi-level metadata approach for a Public Sector Information data infrastructure(2012-06-07); ; This paper describes an approach for representing and handling metadata about Public Sector Information data sets in a large scale data infrastructure as designed within ENGAGE, a project of the FP7 Research Infrastructures programme. A multi-level approach is adopted, allowing management of metadata at various levels of expressive power, and thus enabling different use cases and requirements to be served through a single platform. CERIF is being investigated as a common conceptual model to ensure information integration from diverse sources without loss of meaning and furthermore as the basis for the generation of Linked Open Data. Through detailed mappings from common metadata schemata used for PSI it is shown that CERIF is a data model suitable for representing rich contextual metadata for the domain of governmental datasets. - Some of the metrics are blocked by yourconsent settings
