Proposed Standard: ABCD (Access to Biological Collections Data)
The Access to Biological Collections Data (ABCD) Schema 2.0 is a comprehensive standard for access to and the exchange of data about specimens and observations (a.k.a. primary biodiversity data). It is based on information models such as ASC and BioCISE and incorporates many existing exchange standards. Further information at
http://www.bgbm.org/TDWG/CODATA/Schema/.
Proposed Standard: SDD (Structure Descriptive Data)
Major changes are incorporated in the latest version of SDD:
All object types are derived from abstract base type. ExternalDataInterface grouping given up, all object types, including SDD ones treated symmetrically. Multilingual representation was simplified (one level of nesting less than
previous version). The text character facility was redesigned to be expressed differently in xml, the previous solution was considered unintuitive. This involves element name and structural changes, but no essential changes
in functionality. The expression of measurement units was simplified, rather than allowing multiple units within a character (which required structures to define units and their conversion methods), only one unit may be defined, which may be accompanied with different scientific prefix letters (k, c, m, ) in different descriptions.

Proposed Standard: TCS (Taxonomic Concept Transfer Schema)
The Taxon Concept Schema (TCS) was developed to enable the transfer of taxonomic name and concept data using an abstract model of taxonomic concepts which can capture the range of models represented and understood by the various taxonomic data providers. The model, presented as an XML schema document, has been through several revisions which have been presented in different fora and discussed on the tcs-lc@ecoinformatics.org mailing list and the TCS Wiki at http://tdwg.napier.ac.uk where all previous versions of the schema can be obtained along with related documentation. At TDWG 2005 TCS v1.0 was voted to be recommended as a TDWG standard. Minor issues were discussed
and proposals for minor changes to TCS are being accepted until 30th September at which point TCS v1.0 will be fixed for the ballot. Discussion on minor changes continues on tcs-lc mailing list and the final version 1.0 will be posted on the Wiki.
