Abstract: Methods and apparatus, including computer systems and program products, that implement a description language and a parser for a description language. A method includes receiving input including a specification of base items, a specification of contexts, and a specification of a selected context from the contexts. The method further includes generating an output set of items by evaluating the selected context. In that method, each item in the output set of items includes core attributes of a corresponding base item and can include attributes from a context. Generating an output set of items can include generating a specific bill of materials.

Abstract: Methods and apparatus, including computer program products, for generating an executable program, including receiving serial compile commands in a pseudo-compiler to compile source code modules, scheduling the serial compiler commands in parallel compilers to compile the source code modules, compiling the source code modules in the parallel compliers to generate object code modules, sending compiler completion acknowledgements to a synchronizer and linking the object code modules in linkers in response to linker initiation commands from the synchronizer.

Abstract: Methods and apparatus, including computer program products, relating to transferring data in a diverse file system landscape. In one general aspect, a computer program product can cause a data processor to extract a first one or more file system objects from a self-extracting program, where the first file system objects include file system objects converted from a first type of file system object of a first file system to a second type of file system object of a second file system; and convert the first file system objects to file system objects in the first file system. The second file system can store file system objects of the second type and cannot store file system objects of the first type. The file systems can be the library and root file systems of IBM's iSeries computing system, and the self-extracting program can initiate execution of an Integrated Language Environment program.
