Day-by-Day (in reverse chronological order)

July 2017

• July 5: add invention title to proper grouping of assignment properties; optimize XML parsing
• July 6: try (unsuccessfully) to understand docid mapping...create exploration scripts
• July 7: catch up on documentation

June 2017

• June 30: powwow with James, Abhi, Ed about optimization issues; discuss document ids, X0 etc with Ed; pinpoint issues with APS doc numbers (see Repro Pat Dat#Gotchas) for more info
• June 29: add logging of copy commands, more chattiness to scripts, debug assignment data failure
• June 28: create examples for expansion to plant, reissue, design patent collection; start optimizing xml
• June 27: write SQL to replicate assignees, extract postcodes for ongoing projects
• June 26: speedup code, abstract in-memory file splitters to avoid repetition and some weird edge cases
• June 25: create mappings for APS, assignment properties, XML 2.5 for data import; run data imports for granted data
• June 23: cleanup hacky models with a better set of abstractions; cleanup IDE warnings; redefine patent-address mapping
• June 22: create postcode<->patent table
• June 21: document granted patent queries and equivalencies
• June 20: sketch out APS driver; discuss patent id problem; further document with evidence the zipcode data validity
• June 19: skim address regular expressions; cursory investigation of patent table
• June 16: create method of getting all data into the database, whether it likes it or not; copy over assignments, granted data using new scheme
• June 15: add more robust error reporting, fix race conditions; build out assignment driver; build out fee event driver; add error logging
• June 14: migrate bulk inserts to copy command; refresh on address data and start in on that; convert processor to multi-threaded application
• June 13: spot check SQL tables; fix broken final case endlessly looping; investigate smarter insert methods
• June 12: add XML printer, use it to inspect applications; extend BaseScraper to fetch patent application data; add applications documentation to my project page; add CREATE of other tables
• June 8: add foreign key inserts; create pretty printer for XML analysis
• June 7: finalize DB abstraction layer; migrate code to bulk inserts; upgrade webserver software and do optimization on RDP postgres with Ed
• June 6: add jdbc; create basic schema; add db interaction; schedule meeting for later in the week
• June 5: look into postgresql; refersh on postgis; add some notes to the Enclosing Circle Algorithm page
• June 1: add RDP git remote; add more documentation to wiki page; refactor downloader scripts; start creation of tooling for interacting with data

May 2017

• May 31: finish copy-pasting attributes into the wiki page; retroactively fill out work log; meet with Ed to discuss next steps
• May 30: update documentation on wiki, restructure large binary files to have more hierarchy instead of a flat listing at the root
• May 29: expand to APS; expand to raw assignment data
• May 27: expand to maintenance fee data
• May 26: create models, translate xmlparser*.pl file into Java; start using builder pattern
• May 25: sketch out OO design of project; download bulk data
