Develop standardized electronic formats suitable for the publication,
dissemination, and storage of numerical data files on physico-chemical
properties of pure substances, mixtures, solutions, and materials
In the era of enhanced electronic communication and world-wide development
of information systems, electronic publishing and the Internet offer
powerful tools for the dissemination of all type of scientific information.
This is now made available in electronic form not only from computerized
databanks, but also from primary sources. However, because of the multitude
of existing properties and variety of modes of presentation, the computer-assisted
extraction of the numerical values of physico-chemical properties from
primary sources is as difficult as before. As a consequence, the use
of these data in Application Programs, their Evaluation, the Publication
in Handbooks, and the storage in Data Banks, still remain a tedious
and expensive operation, in spite of the electronic access to the data.
The objective of IUCOSPED will be to design in cooperation with Data
Publishers, Data Centers, and other Potential Data Users, the standard
computer-readable file formats presenting the numerical data, as well
as the relevant metadata, for each type of physico-chemical property,
as they appear in primary publications. Authors will be encouraged to
submit to the Editor their data in standard electronic format, in parallel
with their article. Neither the printed nor the electronic publication
of articles in primary journals or of the data in secondary or tertiary
data sources need to be affected by the proposed standard formats. Each
Publisher of a primary data source or of secondary or tertiary data
sources may keep the traditional format as appropriate to the community
of users of those sources. The objectives of the standard formats, the
same for all primary publications, is to assure that the datafiles are
clearly, uniformly, and completely documented.
The standardized data files will be disseminated exclusively in electronic
form, most likely only via Internet. A specialized central data information
source, tentatively called DataExplorer, may be created. All primary
data sources producing standard data files of acceptable quality would
be allowed to connect to DataExplorer.
The expected output during 1999 is the following:
- Preparation of the preliminary version of a document on general principles
of standardization of physico-chemical property electronic data files
(codification of properties, chemical systems, references, choice of
primary data and derived data, choice of units for physical quantities,
design of the general structure of the numerical data files, etc.).
- Design of electronic data files for at least 100 specific types of
mainly thermodynamic and thermophysical properties for pure substances
and mixtures, preliminary version. Database with examples and search
program. September 1999.
- Preparation of an Electronic Data Input Program (EDIP), demo version,
making the input of data by Data Generators (Authors) and output of
data by Data Users as comfortable as possible. December 1999.
- Establishment of the IUCOSPED Home Page on the STN Server Europe
(FIZ Karlsruhe), with links to IUPAC and CODATA WWW Home Pages, from
where the standard formats and guidelines are accessible to the interested
scientific community at no cost. December 1999.
- Presentation of the Project at several international conferences.
- Plenary Meeting of IUCOSPED Members and Joint Meetings with IUPAC
Commissions on Thermodynamics (I.2) and Equilibrium Properties (V.6)
(August 10 and 11, 1999) in the frame of the 40th IUPAC General Assembly,
