The following describes how to construct bulk uploads from existing files.
1. Use SearchXml.java to find the original paths + values that you want to work from.
Example: all paths for Croatian
(Search has other options: use -h to see them.)
2. Copy the results (which are tab-delimited) into a file, and use regex, search and replaces, or spreadsheets to get the right format for a config file.
For example, what I find simple is to copy into a spreadsheet, and construct the config line from them:
"locale=bs ; action=add ; new_value=" & B1 & "; new_path=" & C1
Alternatively, for simple cases like the above, you can just do search & replace within the file.
3. Use CLDRModify using Config file to modify/create a file.
4. Sanity Check
5. Either merge into trunk or make a separate file for bulk upload, depending on the ticket description.
