Held in conjunction with 18th International Conference on Web Engineering (ICWE 2018).
More and more data is becoming available online every day coming from both the public sector and private sources. Indeed, the open data movement promises to bring to the fingertips of every citizen all the data they need, whether it is for planning their next trip or for government oversight. Most of this data is available via some kind of (semi)structured format (e.g., XML, RDF, JSON,...) which, in theory, facilitates its consumption and combination.
Unfortunately, this is still far from reality. Our society is gradually opening its data but not building the technology and infrastructure required to enable citizens to access and manipulate it. Only technical people have the skills to consume the heterogeneous data sources while the rest is forced to depend on third-party applications or companies.
The aim of this workshop is to bring together researchers, practitioners, stakeholders and users of Open Data. The focus of the workshop will be on practical engineering approaches (a) to design and develop means for promoting the consumption of Open Data and, by leveraging on well-known existing techniques (e.g., conceptual modeling, data mining, data intelligence, etc.), (b) to design and develop composition mechanism that help combining Open Data sources.

Discussion and wrapping up. Some of the ideas that arose during the discusion were:
WEOD solicits high quality submissions describing original and unpublished results. The topics of interest for the workshop include practical engineering approaches to design and develop means for promoting the consumption of Open Data and to design and develop composition mechanism that help combining Open Data sources.
A non-exclusive list of topics follows:
WEOD is intended to have two sessions:
Our case study illustrates an approach for the discovery, composition and consumption of Open Data sources available via REST APIs described by Open API specifications. The Open API Initiative aims at creating a neutral, portable and open specification for providing metadata for REST APIs.
Initially, one or more data sources described by the corresponding Open API specification are analyzed to discover and understand their domain models (i.e., schemas). These domain models can later be composed to provide a general domain model where similar concepts are merged. Composition links performed in this general domain model are actually API compositions (i.e., two APIs may be composed using the shared domain concept). Finally, end-users can query the general domain model to obtain simple or aggregated information, for instance, if the query makes use of only one API or it is needed to compose data coming from different APIs, respectively.
The following figure illustrates the case study and identifies some scenarios where contributions are welcome.
Some of the scenarios include (but are not limited to):
In order to provide a more specific context for framework application, we next provide a definition of a case study. This case study will be used in the hands-on session to present and discuss different approaches providing a complete or partial solution.
All submitted papers must be formatted in accordance to the information for Springer LNCS authors at http://www.springer.de/comp/lncs/authors.html and submitted in PDF. Accepted contributions will be included into the ICWE 2018 Springer LNCS proceedings.
Submissions and reviewing are supported by the EasyChair system.
WEOD'18 will follow the single-blind review process. Consequently, all submissions should include the names and affiliation of all authors, and this information is made visible to the reviewers. Still, the identity of the reviewers will be kept confidential from the authors.
Papers submitted to WEOD'18 must not be under review elsewhere while under consideration for WEOD'18, nor may they have been previously published elsewhere.
Submissions that do not comply with the required submission format or that fall outside the scope of the conference will be desk rejected without reviewing.
At least one author of each accepted submission must register for the conference and present the work during the corresponding session.
