## this is a list of all solr keys for the webgraph index 'webgraph', an index of all links
## this complete list of keys can be changed; the actual schema is stored in:
## DATA/SETTINGS/solr.webgraph.schema
## the syntax of this file:
## - all lines beginning with '##' are comments
## - all non-empty lines not beginning with '#' are keyword lines
## - all lines beginning with '#' and where the second character is not '#' are commented-out keyword lines
