Workshop Linked Open Data and OpenSearch

The - one day workshop - addressing the two topics of linked data and open source opensearch software took place in ESRIN Conference Room E on 15 January 2013 from h 9 to h 17. 

The workshop is triggered by 3 activities/projects possibly achieving very good synergy:

- the Linked Open Earth Observation Data project addressing linked data (Manolis Koubarakis)

- independent activities on OpenSearch open source sw by Jerome Gasperi, Salvatore Pinto and by Iguassu

- the outcome of the technology project SMAAD (Yves Coene)

 

Draft Agenda for the workshop

Start with current state of the art on the 3 topics above with presentations

Set-up splinter sessions to discuss the details and possibly agree upon follow on activities/meetings.  

h 9-915 ESA introduction and motivation

h 915-10 The LEO project: objectives, planned work M Koubarakis UOA

h 10-1045 SMAAD results (30'), status of Opensearch standardisation activities (15') Y Coene Spacebel

h 1045-1115 Coffee break 

h 1115-1230 OpenSearch Open Source J Gasperi CNES

h 1230-13 OpenSearch Data Access and Dissemination service S Pinto  EGI

h 13-14 Lunch break 

h 14-1430 OpenSearch - Iguassu

h 1430-1530 Splinter sessions 

h 1530-16 Coffee Break 

h 16-17 Plenary summary discussion and actions 

!

Since the objective is to achieve synergy among a number of limited initiatives, no public announcement of the workshop was given.

Conclusions/Actions

- Participation/visibility on grid/cloud harmonisation and profiling work (e.g. the work done by egi) to be addressed at HMA AWG/GSCB

- Work on Linked Open Data Relevant to link EO data to non EO domains

- Plan of work in support/coordination with LEO project to be set up in followin weeks ion order to minimise effort on both sides still maximising synergy

- equivalent of EOP O&M and ISO metadata in RDF.

-        identifiers for satellites, instruments

-        ontologies for keywords (domain dependent, WMO, GEOSS, etc. )

-        RDF for attributes explaining semantics of EOP O&M attributes, classes as done by OGC,

-URI naming conventions start from O&M EO mandatory attributes

- recommendation for instrument/satellite naming convention, explanatory text in analogy to what done by OGC

- ontology/thesaury complement/coordinate with CEOS

- Big Data Workshop in November 2014 provide input in terms of priority themes: multidimemsional db, no sql dbs, distributed dbs, Linked Open Data, Semantic Web,...

- the partcipantys cponfirmed the interest for Linked Data

- OpenSearch convergence -> level of implementation needs to be checked as everything optional! And “compliance” is easy (e.g. relation)

- Many open-source components are ready for reuse 

- Benchmarking to choose right one is of interest

- standardization Grid/Cloud -> EGI is far ahead - the egi work could be taken as refernece

- Synergy needed between the various teams
