The GISELA objective is to guarantee the long-term sustainability of the European – Latin American e-Infrastructure and thus ensure the continuity and enhancement of the Virtual Research Communities (VRC) using it. The project will focus on:•\tImplementing the Latin American Grid Initiative (LGI) sustainability model rooted on National Grid Initiatives (NGI) or Equivalent Domestic Grid Structures (EDGS), in association with CLARA and collaborating with EGI;•\tProviding VRCs with the e-Infrastructure and Application-related Services required to improve the effectiveness of their research, addressing both:o\tCurrent EELA-2 small User Communities;o\tLarger VRCs through "Specialised Support Centres" (SSCs).The GISELA mission is twofold:- Ensure the sustainability of the EU-LA e-InfrastructureThe sustainability of the EU part of the e-Infrastructure being cared of by EGI, GISELA will concentrate on its LA component. The tasks, at each level of the e-Infrastructure are:•\tInstitution: Get all Services fully operational in the Resource Centre (RC);•\tCountry: Implement all Grid Operation Centre (GOC) Services;•\tContinent: Implement all Grid & Network Support Centres (GSC, NSC) Services;•\tSupport a catchall GOC.- Support Virtual Research CommunitiesThe support will encompass:•\tUser Support:o\tProvide access to the EU-LA Infrastructure to VOs represented in GISELA (HEP, Life Sciences, Earth Sciences, etc.);o\tPublicise and support the GISELA e-Infrastructure and Application Services;o\tCollaborate with VRCs or SSCs to the development of integrated services (e.g. gateways).•\tTraining & Dissemination activitieso\tOrganisation of tutorials for single users and VRCs;o\tCoordinate dissemination actions, workshops, Conferences;o\tProduce dissemination material.Grid Services for VRCs will be provided by CLARA on the basis of a business plan using a Life Cycle Product Management (LCPM) approach.
