| + | * A stand-alone version is published in [[http://arxiv.org/abs/arXiv:1008.0181|arXiv:1008.0181]]. | ||
| + | * There's a problem with trying to agree upon the I/O of existing functions in existing codes, because this would restrict coding. This problem arises when directly accessing existing methods within existing codes, such as: | ||
| + | * ''FUNCTION <name> type=<type> args=<# of args> | libName=<name of compiled library> | funcName=<name of function in library> | END_FUNCTION'' | ||
| + | * Agreement about the I/O of these directly accessed functions could tie the hands of the author(s) of the original code. | ||

| + | ==== 4th discussion ==== | ||
| + | * A DLHA reader/writer prototype can be created based on SLHA+. | ||
| + | * FUNCTION I/O should happen via arrays. | ||
| + | * We should consider agreeing about the I/O of existing methods in existing calculators. (For abundance, direct or indirect detection calculations, for example.) Then the authors of the codes could distribute a pre-compiled Linux library from which these methods could be called directly based on DLHA. | ||
| + | * We should specify the number of significant figures (16 was suggested) for numerical values. | ||
