Hi, I'm trying to use the update.py script and is not clear for me what to use for 'url' in the usage line: usage: create.py key url [key=value ...]. Which I'm guessing is just a carry over from create.py. I tried passing the direct link to the dataset: $ ./update.py <my_key> http://localhost:8080/api/histories/0397e7c5778be5ee/contents/45d854c903d27d... name=foobar HTTP Error 404: Not Found 404 Not Found The resource could not be found. No action for /api/histories/0397e7c5778be5ee/contents/45d854c903d27dcf Just to show you this dataset does exists: $ ./display.py <my_key> http://localhost:8080/api/histories/0397e7c5778be5ee/contents/45d854c903d27d...
