1 year ago Technical info for implementers/others:
The following is a description of the format of the files mentioned above:
- each file is UTF-8 encoded text, compressed using gzip compression
- each file is formatted according to the JSON Lines specification1:
- each file is composed of one or more lines:
- every line is terminated by a single LF (newline) character
"\n"and preceded by a JSON string composed only of non-LF characters — the LF is the line delimiter and the file ends after the last line: so the file ends with a delimiter character- each JSON string is a serialized representation of a JSON-LD object
Because there are quite a few files at the URL shared in the original message, I'll include a copy of one (of the "smaller more manageable files") here for reference:
