| The notation for the diagrams in this section is as follows. The rounded rectangles represent IV actions on data and the straight rectangles represent instances of information objects at different stages. The arrow lines link actions and objects as follows: arrows leaving an action connect to IV objects created by the action while arrows entering an action connect IV objects to actions using them. | | The notation for the diagrams in this section is as follows.

| |
− | The data use phase is a bridge phase which sits between processing and acquisition. In this phase, the data is used and may produce new data (raw data) which can in turn be persisted by an RI. The actions that act on data at this point can be provided by same RI exposing the data or by external entities (RIs or other).
| |
− |
| |
− | In the use phase, the RI system is open to the outside world. Users (persons or external systems) can use the services provided to produce new data products.

− | '''Note'''<br>
| |
− | This example is provided for illustrative purposes. The example shows one of many alternatives for performing data processing. Other IV actions and IV objects can be introduced at this stage. Actions and objects not described in the IV of the ENVRI RM can also be incorporated. In the diagram and associated descriptions below, cite data, convert data, produce model, and visualise data are some examples of these types of actions.
| |
− | </p>
| |
| | | |
− | '''Data Publishing''': The first action is Data publishing, the phase of the data lifecycle that precedes data Processing. This action produces three IV Objects: PersistentData, GlobalConceptualModel, and Metadata which are used in the Data Use phase to access and process data.
| |
− |
| |
− | '''Provenance Tracking''': Provenance tracking keeps a log about the the actions and the data state changes as data evolves through the RI systems. The resulting provenance data is a form of metadata which may be of interest for referencing and citing the use of data within and outside the RI.
| |
− |
| |
− | '''Data Processing''': Data Processing produces Persistent Data IV Objects.
| |
− |
| |
− | '''Query data''': This action requests specific persisted data from the RI.
| |
− |
| |
− | '''Do data mining''': This action implies the execution of a sequence of metadata/data request/interpret/result/request which automatically produce or find patterns in the data being analysed. Usually this sequence helps to deepen the knowledge about the data.
| |
− |
| |
− | '''Resolve annotation''': This action implies finding a specific data set from a set of semantic annotation and constrains on those annotations. If the annotation is resolved the result should be a link or a set of links to specific data sets, if not the result is an empty set.
| |
− |
| |
− | '''Query metadata''': This action requests specific persisted data from the RI using metadata as additional parameters for narrowing down the search.
| |
− |
| |
− | '''Query provenance''': This action requests specific persisted data about the provenance of some data or metadata. This is usually done to determine the origin and validity of data but can also be helpful for citation and referencing.
| |
− |
| |
− | '''Cite data''': Produce a reference to persistent data or metadata.
| |
− |
| |
− | '''Convert data''': converting and generating data products, for instance translating to a different format.
| |
− |
| |
− | '''Produce model''': creation of statistical models, simulation models or summaries with the data provided.
| |
− |
| |
− | '''Visualise data''': creating visual models which display data alpha-numerically, graphically, or geographically.
| |
− |
| |
− | '''Data Acquisition''': Use of data has the potential for creating data products which may need to be persisted, re-initiating the data lifecycle. For this reason, the the last action after Data Use actions is Data Acquisition.
