The cache databases for DiversityCollection are designed as sources for preformatted data for publication in e.g. public user portals like GBIF. For an introduction see a short tutorial . The cache database by default has a name corresponding to the main source database, e.g. DiversityCollectionCache and is located on the same server and by itself is the source for the data in Postgres (Version 9.4 or above) cache databases located on any Windows or Linux server (see image below). An overview for the basic steps is provided in chapter Basic steps for publication of data via the cache database.
To create a cache database you need to be a system administrator (s. Login administration). The creation of the cache database is described in the chapter Creation of the cache database.
The publication and transfer of the data is always related to a project. Every project has its own database schema containing the data tables etc. The metadata are defined via settings in a DiversityProjects database. The Projects module provides a stable identifier for each Project. The basic address has to be set in the Project module (choose Administration - Stable identifier ... in the menu). Please turn to the module DiverisityProjects for further information. The metadata will be transferred into a table in the cache database. For further details see chapter Projects in the cache database.
As well as data from DiversityCollection, data from other modules like DiversityScientificTerms containing terms, DiversityTaxonNames containing the taxonomy, including accepted names and synonyms are transferred into the cache database and may be retrieved from the local server or a linked server. The data of these sources are stored and transferred independent from the project data. For further details see the chapters about agents, terms and taxonomy.
