+While working today on an annotation class in Python I stumbled on a problem. Normally I work with lists of genes that are consistent, i.e. all Entrez Gene IDs (or RefSeq IDs, or Genome Browser IDs...), but today I had a list of mixed identifiers.
+
+The subsequent idea was "let's implement auto-detection of common identifiers in the class". The problem is... is there any actual documentation on how identifiers are made? So far, using regular expressions, I've tracked down a few:
+
+
+
+	
+  * RefSeq
+
+	
+  * GenBank
+
+	
+  * Entrez Gene
+
+	
+  * UCSC Genome Browser
+
+	
+  * Ensembl
+
+
+However, I have no idea if I have implemented all types of these IDs. Does anyone know a place where to look these information up?

+(On a related note: my thesis defense will be on January 14th, 2008, so I have to get the printing going)
