More than 4 years ago (!) I blogged about about a simple tool I'd written to export your Delicious* bookmarks to Google Bookmarks. With the recent confusion over Delicious's future the tool is receiving renewed interest. I had never updated it to support the V2 API (which is OAuth-based), and the blog post just kept accumulating comments from people that had merged their Delicious accounts with their Yahoo! IDs and couldn't use it anymore.
Having some free time this weekend, I decided to retrofit V2/OAuth support. The only gotcha encountered is that the V2 API requires HTTP, while the V1 API requires HTTPS, but if you get this wrong you get a misleading
signature_invalid response. I also moved all the code to App Engine. Finally, all exported bookmarks get a "delicious-export" label, and ones that were private also get a "delicious-private" label.
* Or del.icio.us, as they were back then.
Update on 12/25/2010: The code is now available on GitHub.
Update on 2/17/2011: Google now has an official tool for importing from Delicious.
