 +  * micrOmegas includes an SLHA reader/​writer which could be generalized for DLHA. 
 +    * 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.
