The Blue Cloud Data Discovery and Access Service (DD&AS) is one of the core
components of the Blue-Cloud technical framework. It It facilitates
discovery and retrieval of marine data sets and data products from blue
data infrastructures (BDIs), such as key EU infrastructures such as
Copernicus Marine Service, EMODnet, SeaDataNet, and more, for external
users in stand-alone mode. It interacts with the Blue-Cloud Virtual
Research Environment, the component federating computing platforms and
analytical services, for populating the VRE data pool. As part of the
predecessor pilot Blue-Cloud project, the first operational release of the
Blue-Cloud DD&AS has been deployed. The current version of the service is
federating in total 8 BDIs and with 9 data services. As part of the
Blue-Cloud 2026 project, it is planned to expand the DD&AS federation with
data discovery and access services from 4 new BDIs, namely: • European
Multidisciplinary Seafloor and water column Observatory (EMSO) • Svalbard
Integrated Arctic Earth Observing System (SIOS) • ELIXIR - MGnify • EMODnet
Physics. The implementation of the Blue Cloud DD&AS largely depends on
machine-to-machine interactions between central components of the DD&AS and
web services / APIs as managed and operated by the BDIs. In this
deliverable a short overview is given of the current architecture and
functionality of the Blue- Cloud DD&AS to provide good insight in the DD&AS
conceptual principles. Per each new BDI a description is given of their
organisation, structure, aims, contents, data discovery and access
services, and available web services and/or APIs, followed by an assessment
of how each BDI might be federated in the DD&AS, fitting into the overall
concept. The gathering of information about each new BDI and the follow-up
analyses and assessment have been performed thanks to a two-way dialogue
between MARIS and CNR-IIA, as core DD&AS developers, with each of the new
BDIs and associated technical providers. This activity started at the
plenary WP2 working session at the Project Kick-Off meeting, on 13–15
February 2023 in Pisa – Italy, and continued during the the first Technical
and Scientific Committee (TSC) meeting, 28-29 March 2023 in Amsterdam –
Netherlands. Since then, the managers of the new BDIs have compiled
information about their BDI and services, following a provided template.
Bilateral web conferences followed with managers of each of the BDIs during
August – October 2023 to discuss findings and suggestions for the
federation. This consultation phase resulted in concrete plans for
federating each of the 4 new BDIs, which are documented in this Deliverable
D2.2 - New Blue Data Infrastructures – Service Analysis Report. These plans
will be worked out and taken into development in the coming period as part
of the WP2 activities.
