Basis set entity Example 1. (eCCP) This is an example of an XML Gaussian atomic basis set (6 31G). 3047.524880 457.369518 103.948685 29.210155 9.286663 3....
Grid entity Example 1. (VTK) This example shows a HOMO and LUMO grid using the VTK XML format (not all the data is displayed). 9.22677458E 04 1.75676935E...
Array Entity Example 1. (CML) The dictRef attribute is used to point to an XML dictionary entry that provides information on the type of data held in the element....
Molecule entity Example 1. (CML) Question: What data should be included as part of the molecule entity? For example, should the molecular name, charge and spin multiplicity...
The data model design A way of specifying XML representations for quantum chemistry concepts is required, and can be achieved using W3C XML schemas. XML schemas are...
Metadata and provenance In addition to representing quantum chemistry data, there is a requirement to be able to represent metadata. This would include data such as...
The relationships between concepts If a modular approach is adopted for the data model, the representation of the concepts alone is not enough. It is also a requirement...
General data containers In some cases, it is a good idea to group concepts into classes and attempt to find a common representation for the class. For example, there...
Existing XML languages with relevance to quantum chemistry The domain of computational chemistry is fortunate in that XML representations already exist for a number...
Adoption of a markup language The first step in developing standards for computational chemistry data requires specification of the concepts that need to be considered...
