=3D=3D MOTIVATION =3D=3D=C2=A0

There is a vast and rapidly increasing quantity of scientific,=C2=A0
corporate, government and crowd-sourced data published on the emerging=C2=
=A0
Data Web. Open Data are expected to play a catalyst role in the way=C2=A0=

structured information is exploited in the large scale. This offers a=C2=A0=

great potential for building innovative products and services that=C2=A0
create new value from already collected data. It is expected to foster=C2=
=A0
active citizenship (e.g., around the topics of journalism, greenhouse=C2=A0=

gas emissions, food supply-chains, smart mobility, etc.) and world-wide=C2=
=A0
research according to the =E2=80=9Cfourth paradigm of science=E2=80=9D. T=
he most=C2=A0
noteworthy advantage of the Data Web is that, rather than documents,=C2=A0=

facts are recorded, which become the basis for discovering new knowledge=C2=
=A0
that is not contained in any individual source, and solving problems=C2=A0=

that were not originally anticipated. In particular, Open Data published=C2=
=A0
according to the Linked Data Paradigm are essentially transforming the=C2=
=A0
Web into a vibrant information ecosystem.=C2=A0

Published datasets are openly available on the Web. A traditional view=C2=
=A0
of digitally preserving them by =E2=80=9Cpickling them and locking them a=
way=E2=80=9D=C2=A0
for future use, like groceries, would conflict with their evolution.=C2=A0=

There are a number of approaches and frameworks, such as the LOD2 stack,=C2=
=A0
that manage a full life-cycle of the Data Web. More specifically, these=C2=
=A0
techniques are expected to tackle major issues such as the=C2=A0
synchronisation problem (how can we monitor changes), the curation=C2=A0
problem (how can data imperfections be repaired), the appraisal problem=C2=
=A0
(how can we assess the quality of a dataset), the citation problem (how=C2=
=A0
can we cite a particular version of a linked dataset), the archiving=C2=A0=

problem (how can we retrieve the most recent or a particular version of=C2=
=A0
a dataset), and the sustainability problem (how can we spread=C2=A0
preservation ensuring long-term access).=C2=A0

Preserving linked open datasets poses a number of challenges, mainly=C2=A0=

related to the nature of the LOD principles and the RD=46 data model. In=C2=
=A0
LOD, datasets representing real-world entities are structured; thus,=C2=A0=

when managing and representing facts we need to take into consideration=C2=
=A0
possible constraints that may hold. Since resources might be=C2=A0
interlinked, effective citation measures are required to be in place to=C2=
=A0
enable, for example, the ranking of datasets according to their measured=C2=
=A0
quality. Another challenge is to determine the consequences that changes=C2=
=A0
to one LOD dataset may have to other datasets linked to it. The=C2=A0
distributed nature of LOD datasets furthermore makes archiving a=C2=A0
headache.=C2=A0


=3D=3D IMPORTANT DATES =3D=3D=C2=A0

- Submission: =46riday 4th March=C2=A0
- Notification: =46riday 1st April=C2=A0
- =46inal version: =46riday 15th April=C2=A0
- Workshop: 30th May=C2=A0


=3D=3D TOPICS =3D=3D=C2=A0

- Change Discovery=C2=A0

* Change detection and computation in data and/or vocabularies=C2=A0
* Change traceability=C2=A0
* Change notifications (e.g., PubSubHubPub, DSNotify, SPARQL Push)=C2=A0
* Visualisation of evolution patterns for datasets and vocabularies=C2=A0=

* Prediction of changes=C2=A0

- =46ormal models and theory=C2=A0

* =46ormal representation of changes and evolution=C2=A0
* Change/Dynamicity characteristics tailored to graph data=C2=A0
* Query language for archives=C2=A0
* =46reshness guarantee for query results=C2=A0
* =46reshness guarantee in databases=C2=A0

- Data Archiving and preservation=C2=A0

* Scalable versioning and archiving systems/frameworks=C2=A0
* Query processing/engines for archives=C2=A0
* Efficient representation of archives (compression)=C2=A0
* Benchmarking archives and versioning strategies=C2=A0

Ideally the proposed solutions should be applicable at web scale.=C2=A0


=3D=3D SUBMISSION GUIDELINES =3D=3D=C2=A0

Papers should be formatted according to the Springer LNCS format. =46or=C2=
=A0
submissions that are not in the LNCS PD=46 format, 400 words count as one=
=C2=A0
page. All papers should be submitted to=C2=A0
https://easychair.org/conferences/=3Fconf=3Dmepdaw2016.=C2=A0

We envision four types of submissions in order to cover the entire=C2=A0
spectrum from mature research papers to novel ideas/datasets and=C2=A0
industry technical talks:=C2=A0

A) Research Papers (max 15 pages), presenting novel scientific research=C2=
=A0
addressing the topics of the workshop.=C2=A0

B) Position Papers and System and Dataset descriptions (max 5 pages),=C2=A0=

encouraging papers describing significant work in progress, late=C2=A0
breaking results or ideas of the domain, as well as functional systems=C2=
=A0
or datasets relevant to the community.=C2=A0

C) Industry & Use Case Presentations (max 5 pages), in which industry=C2=A0=

experts can present and discuss practical solutions, use case=C2=A0
prototypes, best practices, etc., in any stage of implementation.=C2=A0

D) Open RD=46 archiving challenge (max 5 pages), is intended to encourage=
=C2=A0
developers, data publishers, and technology/tool creators to apply=C2=A0
Semantic Web techniques to create, integrate, analyze or use an archive=C2=
=A0
of linked open datasets. Thus, we expect developments showcasing=C2=A0
developments demonstrating one (or all) of:=C2=A0
- useful functionality over RD=46 archives=C2=A0
- a potential commercial application or RD=46 archives=C2=A0
- tools to support/manage RD=46 archives at Web scale=C2=A0
