Introduction: Representing Scientific Data on the Grid
The datasets for many scientific users are stored in very large (tens
of gigabytes), binary files, often one or more large arrays or tables.
Tools for reading and manipulating these files are often written in
languages like Fortran with primitive file handling capabilities. Although
it is possible to represent such data in XML, there are drawbacks:
This is unhelpful for scientific users because common operations such as extracting a slice or a diagonal are hard to do.
However, there is enormous value, and interest, in representing the ‘metadata’ associated with the data in XML. The meta- data will typically describe such things as how the data was produced (parameters, algorithms used etc), when and by whom. It would be very useful if that metadata also contained a description of the structure and representation of the data itself. BinX is a proposal for an XML Schema to address that need.
What is BinX?
, BinX is the Binary XML Description
What is the BinX library?
The BinX library allows the reading and writing of BinX XML files and
the associated binary data. It supports (or will support) functionality
The BinX library is currently written in C++ with bindings to other languages in progress.
How does BinX Work?
When to use BinX?
Where easy transport or transformation of binary data is a concern.
has identified a number of areas
where BinX can be applied now:
The BinX Editor (BinXed) is a visualisation tool to help design BinX documents. A BinX document (as shown in the diagram above) is an XML text file based on the BinX mark-up language for the purpose of describing a binary data file.
The BinX Editor is a Java application which has been developed using Java version 1.4.2 for Solaris, Linux and Windows. The compressed Java archive (InstallBinXed.jar) can be downloaded by clicking on the Download BinX Editor button. To install on Solaris and Linux use the following command: java -jar InstallBinXed.jar . To install on Windows, double-click on the file to start the installation.
