Thanks for the good tips given already
The data is just records of users accessing data. I don't think there is existing modules for this data as it is very specific for this log and not generally used.
the fields could have e.g. mt=image/gif (media type downloaded, could be any mime type really...)
Also there is field for browser type e.g. "bt=Mozilla/4"
A real example would look like this:
at=200802221200/cs=59278/(9)mt=image/gif/(9)bt=Mozilla/4...
Which tells the time of access to media (at) the content size (cs) media type (mt) and browser that was used to access the content (bt). There is about 100 different field names and they all are 2 letter combinations followed by "=" and then the value ending with the field separator "/", which I btw can't unfortunately change.
Maybe the data could be split somehow with the fieldnames like KevinADC suggested.
Thanks
