recommended values of the fundamental physical constants: 1998 Reviews of Modern Physics 72, 351-495 (2000), (current version available at http://physics.
The recommended CODATA

The data-transfer approaches associated with this data capture and storage effort are being coordinated with CODATA
, which has been developing (a) a markup language called the Gas Hydrate Markup Language (GHML) [13-16] for communicating gas hydrate data throughout the research community and (b) an international hydrate portal technology for centralized access to a number of database efforts.
Figure 19 illustrates how this NIST evaluation fits in with respect to other laboratory evaluations of previous years, including the CODATA
assignment of 1986.

The numbers published in the tables were obtained from the 1998 CODATA
least-squares adjustment of their values carried out in the Fundamental Constants Data Center at NIST in 1999.

Two new publications that give selected subsets of the CODATA
