Value Chain of SDI Knowledge Generation Sample Clauses

Value Chain of SDI Knowledge Generation. When analysing the requirements of SDI services for the terrestrial, atmospheric and marine sphere, the following six roles may be identified each of which contributes to the generation of SDI knowledge and are therefore part of the value chain:  Observer, being the initial source of information about the environment. This may reach from sensors measuring weather conditions to citizens observing species occurrences.  Publisher, making a resource, such as an observation, discoverable to a wider audience, e.g. by providing required resource descriptions (metadata).  Discoverer, being the entity that finds a resource, e.g. species occurrence data, based on all available descriptions.  Service Provider, making information or an SDI model accessible to (and usable by) the wider audience, e.g. by offering a standard based service for data download.  Service Orchestrator, being responsible for combining existing services in a way that they create information for a distinct purpose, i.e. an SDI application focusing on a particular sphere, such as terrestrial biodiversity.  Decision Maker, consuming an SDI application in order to retrieve decision supporting material and making a final decision based on the information available, e.g. designating a new protected area. Consequently, the process workflow can be summarized as in Figure 2‐4. Note that workflow services may themselves get published in order to serve as building blocks for more complex SDI solutions.
