Still real suitable systems or application fostering the enrichment of environmental resources in order to make them better understandable and/or discoverable for a broader community are missing or have not be thought of yet. TaToo (Tagging Tools based on a semantic discovery framework, FP7 project, www.tatoo-project.eu ) intends to demonstrate how the enormous amount of environmental information can become better discoverable and understandable for a broad range of user, e.g. from environmental experts up to the man on the street. Clearly upfront to the definition, specification and implementation of the TaToo framework and tools the requirements with respect to environmental resources handled in TaToo (e.g. environmental data, services, applications etc.) have to be defined. TaToo deals with three scenarios, playing a two folded role. On the one hand they are key providers for challenging requirements but they are also the evaluation facility to prove (as domain experts) the results of project. The proposed paper will describe: a) the main categories of requirements (incl. the approach of requirements collection) written down e.g. for tagging, cross-domain annotation and discovery, meta-information, ontologies, etc. b) brief overview on the tools and services for tagging and discovery provided by the TaToo project c) description of Validation Scenario on Climate Twins Regions and its requirements as well as usage of TaToo developments d) the expected impact on Europeans Single Information Space and its environmental society/communityText/Conference Paper
