Quality Assurance Standard
records in the BDWD pass through four levels as outlined below. Each record
has a verification code which indicates the level of review the data record
has passed. When records have passed all levels of quality review, they are
certified by having the name(s) of the specialist(s) responsible for the final
review and the date of the review attached. Records, which have not been
peer-reviewed (levels 1-3), represent research in progress and are
marked with "Warning Work Record." These records should not be used
unless they have been independently verified by specialists as to their
appropriate taxonomic and nomenclatural status. They are made available
here only to aid those contributing to the BDWD.
Name records are linked to their appropriate reference
records independent of the review level. However, name records with the level 3 or higher should be linked.
See under Status for our progress as
well as our work plan for achieving these levels of quality.
Basic Data Entry [BDE]. Level
Data about names are derived from a number of
secondary sources which vary greatly in their quality and comprehensiveness.
What these sources are and how they were used are documented in the Source
and Status documents. All data were transcribed from these sources,
so in addition to errors in a source itself there may be data entry errors.
Also, data entry was done over a number of years and with different
computers, starting with a Wang VS computer system back in 1980s and evolving
into the current FileMakerPro system now used. Hence, errors may have been
introduced in the conversion process. However, with regard to these
possibilities, we believe on the whole the quality of these records are high.
All these records are identified by having a verification code of 40 or less. The BDE work was completed for all extant families on 1 June 2004. Only
fossil Diptera names remained to be entered.
Preliminary Data Review [PDR]. Level 2a
Once the initial data entry is completed the name records may
be compared to the original secondary source or other secondary sources to
identify and correct data entry errors. The records which have had preliminary review will have a
verification code of 41 or greater.
Linkage [LINK]. Level 2b
Name records when checked against their secondary source and linked to their bibliogrphic record are given a verification code of 70 or higher.
Completed Nomenclatural Review [CNR]. Level
Name records that are compared against the
original source by the editors or specialists are identified by a
verification code with the last two digits of 90 or higher.
Completed Taxonomic Review [CTR]. Level
Name records are also reviewed by specialists
to confirm that they reflect the current accepted taxonomy and nomenclature.
Name records which have had their taxonomic status reviewed will have
a verification code raised above 100. Users need, however, to be aware
that verfication of details against the original source and
verification of the current taxonomic status are independent
activities. Hence, a record with a verification code of 150 means that
a specialist has confirm the current taxonomic status of the name but
has not verified the details against the original source.
Peer-reviewed (final) [FIN]. Level 4
Sets of names,
usually all the names for a family-level taxon, which have been reviewed by
specialists, are also reviewed by two independent specialists. These sets of
names correspond to what traditionally have been called catalogs, having
authors and publication dates. For the near term, authors will be encouraged
to have these sets of names also published in printed form. When the
records have passed peer-review they are identified with the name of the
authority and the date of the publication if printed, or if not, the date of
the peer-review. The verification code of these records is raised to over
200. Level 4 records, if not separately published in print form, are to be
considered published online in BDWD. Only these records are available for
