WP5: System architecture | Emodnet Biology

WP5: System architecture

Lead: VLIZ


The main objective for WP5 is defined in Task 3, to develop a complete and robust machine to machine (M2M) interface to transfer data and products in bulk, which is easily accessible for other machines and initiatives, like the EMODnet Central Portal,the European Open Science Cloud (EOSC), Digital Earth and other EU initiatives. This will allow that all the data, metadata and data products that are created and mobilised during previous phases, as well as phase IV of the project, will be made available (in a way that follows the FAIR principles).

The EMODnet Biology M2M interface will be maintained throughout the duration of the project and its users, usability and effectiveness will be monitored.

We will build further upon the Open Geospatial Consortium (OGC) webservices that have been developed during the previous EMODnet Biology phases. A set of new standards and infrastructure technologies will be added in order to meet the requirements described in this tender and discussed in detail under the M2M interface components.

Finally, within Task 9 the maintenance of the existing thematic web portal for EMODnet Biology will ensured for at least 6 months from the start of the contract.


Methodology & Activities

In order to improve the required technical infrastructure to allow a M2M client interface to find, download and subset metadata, data and data products, in bulk, EMODnet Biology will build upon the developments of the webservice implemented in the previous phases of the project. Based on the Central Portal requirements (out of scope of this tender), a number of new technologies will be further analysed, tested an implemented, as will be summarised further ahead.

The current technologies that will be evaluated and upgraded are:

  • PostgreSQL (raw occurrence records and data products)

  • Geoserver (OGC webservices)

  • Geonetwork (ISO19115 metadata)

New server technologies that will be evaluated and, if feasible, implemented include (but are not limited to):

  • Open-source Project for a Network Data Access Protocol (OPeNDAP),

  • THREDDS Data Server (TDS)

  • Other technologies, to be defined
