8. EGEE’06, Geneva, 25-28 September 2006 BalticGrid Data repository in SIG To add data via Plone Content Management System you must: Open http://sigbalticgrid.dyndns.org site in your browser. http://sigbalticgrid.dyndns.org Be a registered user (registration via http browser) and log to the system via http browser. In Resources select repository for your Special Interest Area (i.e. Text-to-Speech repository) and add any type of data by click Add Item button. Some data (i.e. text or sound) is automatically recognized by the system and can be viewed directly in browser.

9. EGEE’06, Geneva, 25-28 September 2006 BalticGrid Data repository in SIG Advantages of using Plone Content Management System as data repository: Easy access to data by using web browser. No addition installations are required to access data. Access for data viewing could be given even for unregistered users, so more people could participate in SIGBalticGrid activities. Disadvantages of using Plone Content Management System as data repository: Data can only be viewed but can not be used on-line in collaboration with other members of SIGBalticGrid. To line up: Plone Content Management System as data repository in SIGBalticGrid can be used for sharing any type of data that does not require on-line applications that use this data. That data could be: first of all publications, reports or any other special data.

10. EGEE’06, Geneva, 25-28 September 2006 BalticGrid Data repository in SIG To add data via Access Grid you must: Download and install Access Grid Toolkit (current version is 3.0.2) from http://www.accessgrid.org site. http://www.accessgrid.org Have your BalticGrid certificate installed. Use your Venue Client application to connect to https://mifaccessgrid.dyndns.org:8000/Venues/default. https://mifaccessgrid.dyndns.org:8000/Venues/default To add data simply click Add Data button in your Venue Client application.

11. EGEE’06, Geneva, 25-28 September 2006 BalticGrid Data repository in SIG Advantages of using Access Grid as data repository: Shared data can be not only viewed but also used by shared Access Grid applications, in other words data not only can be viewed but also modified and used collaboratively. Disadvantages of using Access Grid as data repository: Access Grid Toolkit downloading and installation can make data sharing more difficult (i.e. when data is shared from different computers). To line up: Access Grid as data repository in BG SIG can be used for sharing any type of data but primary for data that require on-line applications/computations that use this data.

12. EGEE’06, Geneva, 25-28 September 2006 ■ Summary: ■ Special Interest Group (SIG) concept is being developed as an application in BalticGrid project (www.balticgrid.org). SIG is going to be implemented as a public service based on grid technology. The main task of SIG is to enable group-to-group communication of scientists and researchers, having similar or related R&D interests (to create virtual spaces). The functionality of SIG is based on grid computing infrastructure, introducing new possibilities and features to a virtual space. Beside teleconferencing, which is most standard function in such case, other functions may be offered: application- (computing-), resource-, data-, file-, desktop sharing, some others. The software for SIG is based on AccessGrid open source software, with many modifications, adds, additional components for the BalticGrid environment. As a collaboration tool SIG provides participant information, data storage, BalticGrid services, application sessions. Research areas under consideration for SIG to be developed and implemented are: Baltic Sea Eco-System Modelling; Text Annotation Service; Text-to-Speech Service; Stellar Spectra Computation; Atomic and Nuclear Computations; Computational Modelling of heterogeneous Processes. www.balticgrid.org ■ Invitation to collaborate: ■ algimantas.juozapavicius@maf.vu.lt BalticGrid
