Dear all, I am trying to tag datasets with hashtags (so they propagate) with tags like #key:value . The idea is to transport information through the workflow that is used at the end of the WF by a custom tool to rename and organise datasets depending on their tags I can do this in the GUI: I tag datasets manually with "#key:value” tags, create a collection with all of them and run a WF => the tags properly propagate. However, when I try to do the same using the collection tool “Tag elements from file”, it does not work properly : the tags are visible in the collection produced by the “Tag elements from file” but are not propagated. I assume this means that the “Tag elements from file” escapes the “#” somehow and my tags are simple tags, not hashtags. Note that my input file is like : element_identifier1 #key1:value1 #key2:value1 element_identifier2 #key1:value2 #key2:value2 Now the questions : - Is this a bug or intended ? - where can I find the file “tag_collection_from_file.xml”, I can t locate it :-/ - any suggestion for a fix ? Thx a bunch Charles
