Hi, Although I feel interested by Piper project, I followed a bit the Loci project, but I am new to lot of things there, so it is likely that I am not aware of some decisions already taken. However, it seems that the Piper XML is not yet completely defined. I am working in the Pasteur Institute and there is a software called Pise: http://www-alt.pasteur.fr/~letondal/Pise/ written by Catherine Letondal (letondal at pasteur.fr). In two words, this is an interface builder. It makes HTML pages and CGI scripts for unix programmes related with Biology. My point is it uses XML to describe the program to be interfaced. This program is under GPL and well documented. I think it would be great if Piper and Pise could share the same DTD... Pise DTD http://www-alt.pasteur.fr/~letondal/XML/pise.dtd I also think that Pise is a working program with some (short) history now and maybe Piper could benefit from the maturity of its DTD. Although Catherine Letondal is not willing to modify her code right now, I know that she may accept if the Piper project is willing to adopt her DTD with some (minor) modifications. What do you think of that ? -- Raynald de Lahondes Unite des Virus Oncogenes - Departement de Biotechnologie Institut Pasteur - 25, rue du Docteur Roux 75724 Paris Cedex 15 - FRANCE tel: 01.45.68.84.54 - fax: 01.40.61.30.33 - cellular: 06.15.65.85.08 email: lahondes at pasteur.fr
