Scratchpad workflow. Users independently submit content in Drupal nodes and vocabularies of terms (e.g. biological classifications of taxon names) associated with content. Nodes are grouped into content types (e.g. images, DNA sequences, phylogenetic trees, GBIF maps etc), each of which has specific workflows for data entry and editing. Terms from a vocabulary (e.g. taxon names) common to nodes are used to semantically enrich (tag) content on submission. Tagged nodes can be represented in predefined views according to their content type, and are dynamically aggregated on term pages (e.g. taxon pages) that can be navigated through their vocabulary. Intuitive curation tools allow users to select which nodes to display on term pages. This model provides a highly generic solution to submitting, grouping, enriching, and navigating diverse data types.
