WP9 - Data Access
Presenter: Massimiliano Assante (CNR) - Slides
- New Home Library features in gCube 3.0
This has implications on all the clients of the HL, clients have to deal with ACLs.
The folder created to store search results should be a "non removal" folder, applications can set the privileges they want.
Think about the possibility to index the user workspace via the NKUA machinery. It is needed an approach to (incrementally) harvest the workspace content and to cope with the workspace evolving space.
The new version of the HL is backward compatible, however the requested changes are minor.
The medium-term plan is to replace the Storage Management Lib with the HL, because of a number of facilities offered by the HL including policy management.
WP9 - Data Transfer
Presenter: M. Simon (CERN) - Slides
- Overview of the enhancement on the Storage Manager portlet and demo
- Presentation of the Service and API in order to stimulate integration with the rest of the system
The facility should be revised to deal with the new version of HL, namely ACL.
The layout should be revised, with the goal to serve an average user, e.g. to simplify the offered options.
Since WP9 is over, they are planning to report the activity in WP11 and WP5 (to check).
In the case of Scheduled Transfer it would be nice to implement a filter on the transferred data to only transfer changed files for every scheduled run.
CERN is going to check the effort to implement this change.
WP10 - Data Retrieval
Presenter: A. Antoniadis (NKUA) - Slides
- Federated Search Status and Plan
WP10 - Data Ingestion
Presenter: J. Gerbesiotis (NKUA) - Slides
It might be useful to decouple DB access information (e.g. JDBC) from data schema information while configuring the SQL2XML adapter.
- A ticket has been created for this #2600;
An approach to access the actual payload should be envisaged. It is currently based on IDs.
The priority should be given to:
- data sources that we do not serve yet including:
- Biodiversity data, via SPD and DarwinCore-Archive files;
- GIS data sources, e.g. via GeoNetwork that means CSW;
- These options should be investigated.
WP10 - Data Publishing
Presenter: N. Laskaris (NKUA) - Slides
- new OAI-PMH, OAI-ORE
A long discussion on making publicly available data / metadata. It was clarified that we should not mix the actual data / resource with the metadata that are exposed via OAI-PMH.
From a technical point of view, the machinery is there. It should be up to WP3 to discuss the policy to be implemented.
WP10 - XSearch
Presenter: Pavlos Fafalios (Forth) (remotely) - Slides
- XSearch and Xlink related activities
The configuration of entity linking is based on categories of entities. Specifically, for each category the user/admin can provide the SPARQL endpoint and the SPARQL template query.
The services are not yet implemented. Currently, FORTH is working on the output format.
Although the analysis of a collection of documents is not supported currently, its support is straightforward.
WP10 - OWS
Presenter: Hervé Caumont, Fabrice Brito (Terradue)
- OWS Context API and Visualization tools

WP9/10 WPS and SOS service
Presenter: Hervé Caumont, Fabrice Brito (Terradue)
- WPS status and plans
WP10 - Semantic Data Analysis
Presenters: Carlo Allocca (Forth), Nikos Minadakis (Forth), Yannis Tzitzikas (Forth)
- Marine TLO
- Warehouse
- Warehouse construction process
WP9 - Tabular Data Manager
Presenter: (CNR)
- Tabular Data Manager and its libraries
- Release status: features and capabilities
- Plan for the next releases
WP10 - Data Mining and Visualization
Presenter: G. Coro (CNR)
- Status of the Statistical Manager platform
- Algorithms currently supported
- Distributed R support
- Missing bits
