IMSLP Mining

Prerequisites

• Clone IMSLP Crawling dataset.

  And configure env variables in .env:

   DATABASE_URL=file:/path-to-imslp-crawling/data.db
   IMSLP_FILES_DIR=/path-to-imslp-crawling/files

• Config file in project root direcotry: config.local.yaml

  • pyclients, the OMR python hosts. E.g.

    pyclients:
      semantic: tcp://localhost:12025
      textLoc:  tcp://localhost:12026
      textOcr: tcp://localhost:12027
      brackets: tcp://localhost:12028

• Copy OMR node package to ./tools/libs/omr.
