- HITRAN was designed 40 years ago with a fixed-format suitable for punch-cards. Over time this format has expanded but not fundamentally changed, and its inflexibility is now a major constraint on the information that it can store. A new relational database model for HITRAN and the software tools necessary to query it have been developed and a trial version is available at the URL http://msslsc.mssl.ucl.ac.uk/. The selected data can be returned in various popular formats, including as an ASCII text table, VOTable, and the native 160-byte HITRAN line format. An XML Schema, XSAMS, for representing spectroscopic data, developed as part of the Virtual Atomic and Molecular Data Centre (VAMDC) project, is presented. This EU-funded initiative aims to build a flexible and interoperable e-science environment for the communication of atomic and molecular data. Spectroscopic data represented in XSAMS format carries explicit metadata describing its source and accuracy; this format allows data from different sources to be compared and merged, and has been extended to allow the inclusion of absorption cross section data and relaxation matrix elements for the description of line-mixing effects. XSAMS is currently implemented by several other molecular databases including the CDMS/JPL line list and BASECOL.
