| {\selectlanguage{english}
The European Plate Observing System (EPOS) is an ambitious long term
integration plan addressing the major solid-earth research
infrastructures in Europe. For its large scale and extent it is an
unique initiative which will foster new scientific discoveries and
enable scientists to investigate the solid earth system with
unprecedented ways. A key aspect of EPOS is to provide end-users with
homogeneous access to services and multidisciplinary data collected by
monitoring infrastructures and experimental facilities as well as
access to software, processing and visualization tools. Such a complex
system requires a solid, scalable and reliable architecture in order to
accommodate innovative features and to meet the evolving expectations
of the heterogeneous communities involved. }

EPOS\footnote{ www.epos-eu.org} ended its Preparatory Phase in October
2014 and, being included in the top three infrastructures in the
prioritization list by Competitiveness Council, is -- at the moment of
writing this abstract -- in the process of submitting the proposal for
EPOS IP (Implementation Phase).}
{\selectlanguage{english}
In this framework, the overarching objective of technical Working
Package (WP7) is the design and implementation of the Integrated Core
Service (ICS) platform, supporting the standardised, efficient,
integrated and transparent access to data, data products and services
of the EPOS community}
{\selectlanguage{english}
EPOS architecture\footnote{
\foreignlanguage{italian}{\textcolor[rgb]{0.2,0.2,0.2}{Keith G.
Jeffery, Daniele Bailo. EPOS: Using Metadata in Geoscience, , Metadata
and Semantics Research Communications in Computer and Information
Science Volume 478, 2014, pp 170-184}}} envisages a main system, the
ICS, integrating data and services provided by communities through the
Thematic Core Services (TCS). TCS according to their level of maturity
will build new interoperable services or make existing services
interoperable with ICS through the use of software interfaces allowing
the interchange of metadata with the ICS. }
{\selectlanguage{english}
Therefore WP7 will develop the software for integration while TCS are
responsible for provision of metadata descrivbing their services and
assets, testing and evaluation of the system, provision of use cases,
and creation of software interfaces (APIs, web services, microservices
architecture-based interfaces etc.) and testing and evaluation of the
system,. Importantly, once the ICS-C host country will be selected, WP7
will collaborate with IT experts from the host country for facilitating
the future operation of ICS.}
{\selectlanguage{english}
One of the main elements enabling the system to integrate data, data
products and services is the metadata catalog based on the
CERIF\footnote{ www.eurocris.org} metadata model. Such a model,
modified to fit into the general e-infrastructure design, is part of a
three-layer metadata architecture\footnote{ Jeffery, K., Asserson, A.,
Houssos, N., \& J\"org, B. (2013). A 3-Layer Model for Metadata. Proc.
Int{\textquoteright}l Conf. on Dublin Core and Metadata Applications
2013, 3--5.}. CERIF guarantees a robust handling of metadata, which is
in this case the key to the interoperability and to the capability of
orchestrating the distributed resources made available by EPOS data
providers and stakeholders.}
{\selectlanguage{english}
Contributions by external stakeholders as European Projects dealing with
complementary issues (e.g. data management, data curation) or as
computational infrastructures both at European and National level are
envisaged in order to provide Computational Earth Sciences services to
Thematic Communities and other EPOS users.}
{\selectlanguage{english}
In this work we will present the lessons learned, the technical
achievements of the EPOS Preparatory Phase and the plan for the
Implementation Phase.}
