I had a look at it and believe it should be doable, at least partly. The general approach is already similar – however, IAB relies on Server Logs while Podlove Publisher relies on HTTP Requests. The data available is similar but not identical.
Differences/Issues I see:
Page 10 prescribes a “24 hour window”, Podlove Publisher currently uses one hour. That is easily changed though.
Page 11 mentions: IP blacklists and whitelists maintained by IAB members that are not publicly available and are not meant to be public. Since Podlove Publisher is Open Source I double we will be able to gain access to those lists.
Page 12:
- To count as a valid download, the ID3 tag plus enough of the podcast content to play for 1 minute should have been downloaded
This requires BytesServed data which is not availabe to Podlove Publisher.
In summary, Podlove Publisher can get as close as possible given the technical limitations to the spec but if it will count as compliant, I cannot say.
