Commission Enterprise Architecture Framework



Various models



Functional perspective: domain model



Interchange of Data between Administrations (IDA)

Some requirements

• Metadata– Data accompanying documents– Policies needed

• Document Identification– Naming and addressing documents– Standardised way of identifying, labelling and

addressing documents (and other objects)

• “Semantic Web”– Navigating web sites, intelligent queries

• XML-based ‘common vocabularies’– Common ‘understanding’ between legislators



Injecting over €9bn to boost European Information and Communication Technologies


NESSI

http://www.nessi-europe.eu

Aims to develop a visionary strategy for Software and Services driven by a common Strategic Research Agenda where innovation and business strengths are reinforced.

Expected impact:• standardisation, common service platform open standards• improve EU competitiveness in S&S• reduce sector fragmentation and align R&D efforts• openness: an open initiative mobilising SMEs, academia and industry• address key R&D and policy challenges in S&S

NESSI Working Groups

(Source: NESSI, 2008)


NESSI Semantic Technologies Working Group

• Manifesto: Research areas– Semantic mediation– Automated reasoning– Semantic information integration– Semantic technologies relating to service

description, discovery and composition– Web 2.0 technologies

• Research roadmap 2007-2010– Vision of Semantically-Enabled Service-

oriented Architecture (SESA)– Need for Semantic Execution Environment

Context

Adapting to meet local environment constraints, organizational policies

and personal preferences

Web principles

To scale SOA to a world wide web communications

infrastructure

Web 2.0

As a means to structure human-machine

cooperation in an efficient & cost-effective manner

Semantic Web

To automate service discovery, mediation &

composition

SOA As the emerging dominant paradigm for application development which abstracts from software to the notion of a service

SOA4All

(See also: http://www.soa4all.eu)


SOA4All will integrate the service world of large enterprises, SMEs, and end-users

SOA4All will transform the Web into a domain where billions of parties are exposing and consuming services

enabling them to engage as peers within a network of equals

in a seamless transparent fashion

•How will the Consumer dynamically discover the existence of a Service Provider?

•How can the Consumer locate the Provider?

•How can the Consumer and Provider describe how to connect to each other, in a standard format which can be understood regardless of their IT platforms?

•How can they exchange messages in a common messaging format which is independent of their underlying platforms?

•What data format can they use to exchange data independent of their underlying database technologies?

• Most of the digital universe will remain unstructured

• Tools and techniques will be required to add structure to this content to improve search, discovery, management, security, and storage

• We will be facing serious problems in information:

– finding– extracting– representing– interpreting – maintaining


New roles in services

Distribution of Web Services by CountrySource: SEEKDA (2007)

• Around 10,000 active endpoints described with WSDL files

• Service search engines, service crawlers, e.g. Aleph

• Service brokers, market places, e.g. StrikeIron


Future InternetComing soon…

• Bled conference (March 31 - April 2)

– Bled declaration– Various aspects of Future Internet– Issues paper Internet of Services

• Semantically-enriched services • Enable automatic service discovery,

description, composition, and negotiation• Semantic interoperability to facilitate

composition and middleware support

• Future Internet Assembly

Conclusions

• Semantic interoperability: a hard problem

• Various working groups in the area

• Future Internet likely overarching theme, with semantic interoperability included
