Linked (Open) Data has reached the European Publishing Industry – but is it the ‘Real Linked Data’ – a short review on the Publishers’ Forum 2013

Invited by Helmut von Berg, Director at Klopotek & Partner (Klopotek is THE European vendor for publishing production software) I had the chance to participate and speak at this years Publishers’ Forum 2013 at the Concorde Hotel in Berlin on 22nd to 23rd of April 2013.

Coming from the semantic web / linked (open) data community to this publishing industry event with about 320 participants (mainly decision makers) from small to huge publishers all across Europe made me really curious in the forefront of the Forum – what would be the most important issues for innovative publishing processes, what would be the hypes and hopes of a sector that is in the middle of a big change: coming from paper publishing straight into the world of our todays’ data economy?

And  then in Berlin, Monday morning – the big surprise: already the opening keynotes by David Worlock, Outsell, UK (Title of Talk: The Atomization of Everything) and Dan Pollock, Nature Publishing Group, UK (Title of Talk: Networked Publishing is Open for Business) mentioned topics as the Semantic Web, Linked (Open) Data and even RDF and Triple Stores – last but not least pointing out that the content of publishers needs to be atomized down to the ‘data level’ and then can to be used successfully for new and innovative business models to serve existing and future customers…

David Worlock ‘singing my song’ at the Publishers’ Forum 2013

As I participated in the European Data Forum 2013 (EDF2013) just a few days before the Publishers’ Forum my first thought was: WOW – publishers today have arrived in modern data economy (following already the data value chain)! And I enjoyed talking to David Worlock in the coffee break telling him my thoughts and that I will manage a workshop about ‘Enterprise Terminology as a basis for powerful semantic services for publishers’ in the afternoon that day (see slides on slideshare) and his answer was ‘Yes Martin, it seems that I was singing your song’.

The following 1.5 days of the Publishers’ Forum 2013 were full of presentations, workshops and discussions about innovative publishing processes, new business models for publishers and innovative approaches and services – full of terms that are well known by myself like: meta data management, semantics, contextualisation and very very often: Big Data and Linked (Open) Data…..and I listened very carefully to all of this – and at some point it was clear: this discussion needs to be evaluated more carefully – because many of talks and presentations were using the above mentioned terms, principles and technologies only as marketing buzz words – but taking a deeper look showed: there is no semantic web technology in place?!

Hey, Linked Data does NOT mean to establish something like a relation / a link between ‘an Author and a publication’ inside of a repository / a database – Linked (Open) Data is a well established and specified methodology using W3C semantic web standards:

Tim Berners-Lee outlined four principles of linked data in his Design Issues: Linked Data as follows:

  • Use URIs to denote things.
  • Use HTTP URIs so that these things can be referred to and looked up (“dereferenced”) by people and user agents.
  • Provide useful information about the thing when its URI is dereferenced, leveraging standards such as RDF*, SPARQL.
  • Include links to other related things (using their URIs) when publishing data on the Web.

Please read in more detail here:

As being a bit like an evangelist for Linked (Open) Data I think such a hype can be very dangerous for the publishing industry – because I see a very strong need for these companies to go for innovative content- and data management approaches very quickly to ensure competitiveness today as well as competitive advantage tomorrow – but not using the respective standards (means: only having the packaging and marketing brochures branded with it) cannot fulfill the hopes in the mid- and the long term!

Thereby I would like to point out here that ‘Linked Data’ seems not always to be ‘Linked Data’ – and I would like to strongly recommend to take a look at the well proven standards – and when selecting IT consultants and IT vendors (means: your IT partners – also a very interesting message taken home from the Forum: that publishers and IT vendors should co-operate more closely in the future in the form of sustainable partnerships) to ensure that these partners really have worked already and are working continuously with these standards and mechanisms!

WKD Use Case on Enterprise Terminologies

Btw. I had a great workshop on Monday afternoon together with Christian Dirschl from Wolters Kluwer Germany (WKD) discussing applications on top of enterprise terminologies (controlled vocabularies using real linked (open) data principles). And: The Semantic Web Company (SWC) is already a partner of the publisher WKD – and this partnership seems to become a more and more fruitful and sustainable one every day – using real linked (open) data…

GBPN Knowledge Platform using Semantic Technologies and Linked Open Data launched

The brand new web based GBPN Knowledge Platform has been launched on 21 February 2013. It helps the building sector effectively reduce its impact on climate change!

It has been designed as a participative knowledge hub and data hub harvesting, sharing and curating best practice policies in building energy performance globally. Available in English and soon in Mandarin, this new web-based tool of the Global Buildings Performance Network (GBPN) aims to stimulate collective research and analysis from experts worldwide to promote better decision-making and help the building sector effectively reduce its impact on climate change. To sustain and accelerate change in the building sector, the GBPN encourages open and transparent access to good quality and verifiable data. The data can be used and re-used in HTML, PDF and machine readable raw data (CSV) formats – provided by a Creative Commons Attribution (CC-BY 3.0 FR) license.

The GBPN Knowledge Platform is built on Drupal CMS and seamless connected with the PoolParty Semantic Information Management Platform of Semantic Web Company. Thereby this knowledge platform makes use of semantic technologies and Linked Open Data (LOD) principles and techniques under the hood. A lot of the available data of the various GBPN tools is provided as (linked) open data under a Creative Commons Attribution license. The Semantic Web Company is responsible for conceptual design and technical implementation of the GBPN Knowledge Platform.

As follows an overview and description of the most important features, tools and services of the information management system.

ADMS implemented in PoolParty Thesaurus Manager (PPT) 3.1.0 Release

ADMS – the Asset Description Metadata Schema of the European Commission Joinup Initiative, is a metadata vocabulary to describe semantic interoperability assets.

The Asset Description Metadata Schema (ADMS) is a common way to describe semantic interoperability assets making it possible for everyone to search and discover them once shared through the forthcoming federation of asset repositories.

 

One of the main objectives of ADMS is e.g. to foster cross-boarder services in Europe by the efficient re-use of semantic assets in e-Government.

 

Description of ADMS
ADMS will allow public administrations, businesses, standardisation bodies and academia to:
  • keep their own system for documenting and storing semantic assets;
  • improve indexing and visibility of their own assets;
  • describe semantic assets in a common way so that they can be seamlessly cross-queried and discovered by the community through a single access point (Joinup);
  • retrieve, compare and potentially link semantic assets to one another in cross-border and cross-sector settings;
  • identify assets to be reused avoiding duplication and expensive design work.

Outreach of ADMS
ADMS is the first step towards a federation of european assets repositories. From mid 2012, Joinup will make available a large number of semantic interoperability assets, described using ADMS, through a federation of asset repositories of Member States, standardisation bodies and other relevant stakeholders. Through this federation, semantic interoperability assets will become retrievable and available via a single point of access.

Please consult the ADMS brochure for further information.

 

ADMS implemented in PoolParty Thesaurus Manager (PPT) 3.1.0 Release

 

The current release 3.1.0 of the PoolParty Thesaurus Manager (PPT) of the Semantic Web Company provides now full ADMS capability!

Figure: PoolParty GUI for metadata management of controlled vocabularies – ADMS tab.

 

Therefore PoolParty Thesaurus Manager (PPT) now allows the content architect to fill in the full description of a controlled vocabulary (a SKOS Thesaurus) – means the meta data of a controlled vocabulary – following now also ADMS standards – these ADMS relevant meta data is automatically published with a controlled vocabulary using the ADMS RDF schema and thereby can be used to publish a vocabulary in the repository of Joinup or another relevant repository of semantic assets to ensure re-use of the controlled vocabulary and thereby interoperability for services et al.

 

Example

And: the corresponding ADMS description in RDF:
http://vocabulary.semantic-web.at/semweb/adms/0.1.rdf

More information also available in PoolParty Thesaurus Manager (PPT) 3.1.0 Release Notes.

If you are interested in this topic around Joinup and ADMS as well as the respective PoolParty implementation then participate in the SEMIC2012 conference on 18 June 2012 in Brussels, Belgium.

reegle.info – linked (open) energy data cloud

Access to the latest high quality information on renewables, energy efficiency and climate change is fundamental to the acceleration of the clean energy marketplace, facilitating investments, promoting new legislation and regulations and broadening interest and knowledge in the sector.

reegle.info acts as a unique clean energy information portal, targeting specific stakeholders including governments, project developers, businesses, financiers, NGOs, academia, international organizations and civil society. Alongside comprehensive country energy profiles, energy statistics and a directory of relevant stakeholders it also offers the clean energy search and an extensive glossary. There is also an insightful clean energy blog with interesting and up-to-date background information.

As reegle.info provides relevant clean energy data from several key energy open data sources as for instance OpenEI, World Bank Data or the UK Open Data Portal the reegle.info Information Gateway has a strong need for efficient and automated data management mechanisms and technologies! Therefore REEEP (The Renewable Energy and Energy Efficiency Partnership) decided to use Linked Open Data (LOD).

Linked Open Data provides a powerful way for reegle.info for sustainable data management and data integration – thereby the current reegle.info linked (open) energy data cloud came into being and looks as follows:

The figure of the reegle.info linked (open) energy data cloud above shows the model behind the scenes of the reegle.info clean energy information gateway providing an insight about sources and respective connections / links between the several sources and data sets.

For the realisation of the Linked Open Data based reegle.info system the following software components are in use:

Going this direction the reegle.info clean energy key portal is very flexible for future expansions in the fields of data integhration and data management by new data sets from several data sources!

By the way – reegle.info is very open too – thereby the whole REEEP generated data is available via a Sparql endpoint for free re-use under the UK Open Government Data license on the reegle.info data portal!

Try it out and make use of free high quality clean energy data!
