Annotation Database Entity Documentation

The database is large, complex and relational with a lot of entities describing many facets of ROV operations, measurements and observations.

Notes About Specific Entities

These notes about specific entities complement the generated documentation below.

rov.dive and rov.transect

Dives represent the span of time during which an ROV, submersible or drop camera is in the water, but may also represent the time during which the instruments are operating. In cases when the instrument data are contained entirely within the time span logged by the operator, the times are recorded unchanged. When the instrument data extend beyond the recorded times of the dive, they may be extended. Occasionally, the operator will record an erroneous time, or omit a time altogether. The instrument times can help to reconstruct this history. Dives also relate to important configuration information, objectives, crew and operational notes.

Transects are defined by their start and end times, contained entirely within dives and do not cross the boundaries between dives. They do not have any related entities and function mainly as accounting items. However, they are extremely important in the analysis of observations and measurements collected during the dive. For example, if one is calculating the density of a particular population of organisms, one must know the precise geographic extent of the region. Transects accomplish this and store objectives and operational notes.

In instances where the times of transects are not recorded, or lost, they can sometimes be reconstructed from status events in the observation record (e.g., a VideoMiner database may have transect start/end events). Otherwise, they are not recorded at all. Ideally, transect records are present and their start and end times are recorded without modification, so long as they are reasonable (i.e., the end time occurs after the start time).

Generated Documentation

Database entity documentation is generated from the production database by the script, db_generate_docs.py. The script outputs a file whose contents can be copied into this page after the <!-- BEGIN GENERATED CONTENT --> tag.

The documentation is arranged into conceptual groupings with the following structure.

• Schema
  • Table
  • Materialized View
  • View

System and Django tables aren't included. The ID column of each table is also excluded.

Database Comments

Documentation resides in the database itself, in the form of comments on the relations and columns. Documentations can be created by executing SQL statements in the form,

   COMMENT ON SHCEMA [schema] IS 'This is a schema comment.'
   COMMENT ON TABLE [schema].[table name] IS 'This is a table comment.'
   COMMENT ON COLUMN [schema].[table name].[column name] IS 'This is a column comment.'

Comments are managed using DDL, as described on the Database Upgrades page.

Table: cruise

Cruise legs occur within a cruise and are assigned specific crews, scientific programs, etc. A single leg can cover an entire cruise, legs can be spaced end-to-end, or can theoretically overlap. Legs can share members or equipment, and crew members can have specific roles related to a leg. Cruise legs can be created without a scientific program or a cruise because imported data sets may only list the name of the cruise and not indicate whether it was part of a longer cruise.

Table: status_event

This table records status events with names given by the status_type_detail table. Status events represent a state that changes at some time and persists until another state preempts it. For example, "on bottom" would persist until an "off bottom" event is recorded. A status_event is a specialization of an event.

This is a lookup table for available status types, such as "on bottom" or "off bottom."

Table: status_type_detail

This table associates a status type with a status event. The point of this indirection is to allow the addition of detail relative to the status type.

The status type value is the discriminator for the event, but the detail adds context the doesn't interfere with it.

Table: taxon

The taxon table stores information about the identification of observed specimens. A taxon record stores the name of the taxonomic unit (e.g., the species or genus name), or an open nomenclature (ON) identifier using *sp.* or *cf.*; an optional operational taxonomic unit (OTU), and a reference to any known taxa in the Hart, ITIS, iNaturalist or WoRMS databases. The original label stores the name as imported. The label, OTU and Hart code are updated at audit time from the original label and the scientific and common names are updated if available. The auditing process is necessary to produce reasonable data. Some of this work can be performed automatically. Multiple records in this table can refer to the same species or subspecies. It *may or may not be known whether the species referred to by a record are the same or different.* Some amount of auditing will probably be necessary on this table. The contents of this table are driven by observations; it is not populated from existing catalogues but from observations, and the authoritative entity IDs are populated as a post-processing step from existing catalogs. If a match in one of the authoritative catalogue is not found, the relation fields are left empty and the taxon should be audited, to correct spelling or assign a correct identifier.
