*There seems to be a delay when showing the results in the XSearch portlet. NKUA suggested showing the results derived from the gCube search and when ready display the entities/clusters. FORTH is OK with that.
+
Integration status
−
*There is no paging of the results. FORTH answered they are already working on that.  
+
*X-Search portlet
−
*The returned results are similar to web-search results (rather than gCube results). NKUA suggested showing all the presentable fields. FORTH anticipated that that the title and snippet should be enough (since they had the freedom to present them). However the presentation of all the results is trivial to be done.  
+
**Activity almost complete
−
*NKUA mentioned that there are some presentation issues with the entities tree. FORTH will try to re-produce the bug (according to the NKUA scenario).
+
**Result retrieval from gCube Search
−
*There seems to be an issue with the location of the portlet at the Liferay portal. FORTH mentioned that when adding the portlet there exist two separate panels (a small one and a bigger one). NKUA responded that it is a matter of configuration (of the Liferay portal) and if switching it to have a single layout (covering all the available width of the page) should be enough.
+
**Communication with X-Search Service by means of gRS2
−
*NKUA asked about the entity categories. FORTH answered that it is configurable from the service. NKUA mentioned that in it is required to show different categories for different VREs. FORTH answered that this is correct and they should further investigate it (i.e. by creating several instances of the service, passing the available parameters, etc.).

**A gCube portlet providing such administrative functionality should probably be implemented.

Agenda

Time: Tue, July 31, 2012, 15:00 - 15:30 CET

  • Progress of integration activity between X-Search and gCube Search
  • Planning of remaining activities in accordance with time constraints

Participants

  • Alex Antoniadis (NKUA)
  • Gerasimos Farantatos (NKUA)
  • Rena Tsantouli (NKUA)
  • Giota Koltsida (NKUA)
  • Pavlos Fafalios (FORTH)
  • Yannis Marketakis (FORTH)
  • Yannis Kitsos (FORTH)

Discussion Summary

Integration status

  • X-Search portlet
    • Activity almost complete
    • Result retrieval from gCube Search
    • Communication with X-Search Service by means of gRS2
    • Result presentation
  • X-Search service
    • HTTP RESTful service
    • Development instance currently hosted at FORTH
    • Performs functionality of result clustering and entity mining

Remaining activities

  • Result presentation and the functionality of the X-Search portlet in general must achieve the standards required for usage in the production environment and especially for demonstration during the review.
    • Achievement of this goal will be given high priority among the activities during this week. Specifically for the presentation of content to the user, NKUA will support FORTH in the usage of Content Viewer by the X-Search portlet.
  • The provided functionality currently exploits result snippets. Result analysis over all content using annotated search fields is not supported yet.
    • A discussion regarding the effort needed to include the feature in the final components followed. NKUA felt that this activity is feasible as the effort required is not significant, taking into account that all supporting functionality is available through the Resource Registry.
    • Both partners agreed that the feature should be included in the activity. In order to facilitate integration, NKUA will provide support on the usage of Resource Registry.
  • Integration with FLOD SPARQL endpoint depends on a ticket managed by FAO
  • Discovery and registration of the final version of the X-Search Service to be released should be discussed with CERN.

Further technical topics included

  • Search metadata handling and presentation in the context of result presentation: Discussion included the field model exploited by the Search System, the correspondence of fields with the fields exposed by collections and the functionality of presentation fields.
  • The possibility of performing tests in the production environment. This could enable us to perform tests with the data hosted in production and take advantage of a more stable environment. Most issues encountered during last week in the development infrastructure concerned the failure of Search to answer some queries, some downtime of the Search Service and some problems related to the Information System.

Actions

  • In the coming two days FORTH will work on result presentation in order to attain the standards required for demonstration of the functionality, e.g. functionality and look and feel compatible with the current results portlet
  • In parallel, FORTH will be communicating with NKUA in order to receive support regarding the usage of Content Viewer and the integration with Resource Registry.
  • FORTH will communicate with CERN to discuss details regarding the publication and discovery of the X-Search Service in the production environment and work on any suggestions provided by the latter.
  • Progress and the actions to be performed during the last week of August will be discussed this Friday.
