Google Books, Internet Archive, Commons upload cycle/Progress
Goals for the first half of the internshipEdit
- Create the front-end for the web-tool to be hosted on tools-lab server.
- Develop bot that handles queries in database (time-out deletion/queue handling/IPC-communication messages).
- Extract meta-data from Google-Books and introduce system to check if book already present in IA(Internet Archive).
- Create script to download from Google-books.
- This will be done by extracting individual page image, and then converting'em to pdf.
- I find IRC a quick way to contact to my mentors.
- Email will be used when mentors are not available.
- plan to have involvement of interested parties for testing/ suggestions.
- For this announcement on wikitech-l, wikisource-l, commons-l, will be made.
Lessons learned since 21st AprilEdit
- Every task becomes a piece of cake, if you love doing it.
- For queries, google cannot be as good as a real-time chat/email with someone experienced.
- Before the core-coding, the set-up work does take a lot of time and edits.
- Discussions and feedback make thing better.
