    16 ER diagrams can be built using MySQL Workbench
     17=== ER Diagrams ===
     18We don't maintain ER diagrams for the whole system as it would be too large to be meaningful. Instead we recommend building your own for the relevant modules for your deployment using one of these tools:
     19* MySQL Workbench
     20* dbwrench (for PostgreSQL)

    18 dbwrench could also be used as a E-R diagram modelling tool for Postgres database
     22=== Key/Value Tables ===
     23In order to allow extensibility of the core schema, many resources have key/value 'tag' tables associated with them.
     24
     25This allows supporting many different coding schemes at the same time and could allow interop with triple-store databases via RDF.
