CSIRO Marine Research Data Centre linked databases - CAAB, MarLIN and Divisional Data Warehouse
CAAB - Codes for Australian Aquatic Biota • Holds names and codes for Aquatic organisms of interest to our Division, plus selected other agencies, for use in data storage • Adopted by a variety of other agencies as “de facto” standard for coding fisheries data in the Australian region • Recently (1999) upgraded to hold codes for many other types of organisms • Can hold cross-references to ITIS numbers and other codes • Allows maintenance of the names to be decoupled from maintenance of the data • Searchable via web interface by scientific name, common name or taxon code (or parts thereof) • Can function as a live look-up table for other CMR databases which use codes as internal taxon idendifiers
CAAB “meaningful” codes hierarchy (and “telephone” analogy) • CAAB has 2-digit “major categories” - e.g. 10=Porifera, 37=Pisces, 63=Angiosperms … (country code) • Has up to 999 family codes in each category, in a recognised systematic sequence (e.g. 37 005 to 37 024 are all sharks) … (area code) • Holds up to 999 taxa in each family, assigned as next available number (allows for generic or species reassignment without needing to change the code) … (user number) • “Split” families catered for without changing the code; “lumped” families or taxon transfers may require re-coding • Allows for rapid automated filtering or sorting of data by codes alone
MarLIN - Marine Laboratories Information Network • Divisional metadatabase - holds descriptions of datasets • Uses regional standard (“ANZLIC”) metadata elements, plus agency-level extensions e.g. projects, surveys, vessels, taxonomic groups and CAAB species • Searchable via www (intranet and internet) • Includes structured result sets, sorted by keyword, etc. (similar to GCMD) • All externally accessible records also retrievable via ASDD (Australian gateway for distributed searching) • Records contain on-line links to further resources and actual data wherever appropriate
Lists of titles Dataset “thumbnail + links” pages Example MarLIN search results
New Divisional Data Warehouse (under development) • Builds on a prototype (“SQuID”) developed in 1999-2000 • Designed to hold variety of data types - biological, physical and chemical oceanographic data; photographic data; ships’ tracks; etc. etc. • Uses CAAB taxon codes for internal biological data handling • Will be hyperlinked to “MarLIN” for access to relevant metadata record/s • All records geo- and time- referenced using Oracle spatial options and date fields, interface will use MapInfo tools to display and query the data • Concept is for one DB at present, upgradeable to multiple databases if needed in future
Dispersed resources Web-based search and display of metadata (via MarLIN) Web-based search and display of Australia-wide metadata (via ASDD gateway) MarLIN-ASDD connection MarLIN ASDD CAAB Taxonomic database Data Warehouse Other Organisations’ metadatabases (under construction) Summary - our system overview CMR
future options & plans ... • Build “live” links to data in our data warehouse from MarLIN metadata records • Possibly link multiple DBs / agencies’ data under a single search/display application • Link “MarLIN” to international metadata clearinghouses e.g. FGDC (USA) • Possibly link our agency’s data into a global OBIS • Adopt emerging global standards for taxonomic IDs, keyword thesauri, etc. • Additional population of metadata, data, and taxon definitions into our systems, as source material and resources are available
