Fans and journalists are interested in what works are being created and what works are being deleted.
We want to dump the tags associated with all works created on all days . if this is run repeatedly then as well as each dump giving you what new works where created in a month by comparing two dumps you can see what tags were used on the works which have been deleted and which day the deleted works were created on.
The file format should have the day number starting from the last full day, it should display the start time and stop time of the period with timezone information, It should include the day of the week so that information is easily exposed.
Additionally the first line of the day should list the number of works created.
otherwise the type of tag and the name of the tag and the tag id, followed by how many works used that tag.
