 This guide lays out the format specifications for the *G*ene *P*roduct *I*nformation (GPI) 2.0 format.
 **Note that the GPI file is the companion file for the [GPAD file](/docs/gene-product-association-data-gpad-format/).
 Both files should be submitted together using the same version.**

 GPAD/GPI is intended for internal GO use. GO also provides annotations as [GAF files](/docs/go-annotation-file-gaf-format-2.2/) and reccommends use of the GAF format for most use cases.

 ## GPI Header
 ### Required information to provide in the header:
-All annotation files must start with a single line denoting the file format. The database/group generating the file (as listed in dbxrefs.yaml) & the ISO-8601 formatted date the file was generated must also be included in the header. Example for GPI 2.0:
