I am writing a house rules document for a Pathfinder game. Not publishing it would be a pity, and not using OGL to publish it likewise, since publishing the house rules under OGL allows others to use the same content.
Can I add links to various SRDs in the document?
For example, if I link to the website of Paizo, the link might be http://paizo.com/pathfinderRPG/prd/coreRulebook/gettingStarted.html. The link contains the word paizo, which is designated as product identity in Paizo’s SRD. I suspect that this is also the case with SRDs maintained by third parties.
Quoting or not quoting text from other OGL content
Currently I do not quote any text from any other OGL publication (aside from the license text). Later, I may quote such material, which would make it necessary for me to attribute the text to its proper source. Suppose the source is a Pathfinder product (and the quoted text is open content). Does this change the answer to the first question?
Content of the document
The document has content such as: “Player may choose zero or one traits for the character, or two traits and one drawback.”
It also contains more substantial content, such as a rewritten version of the content of this blog post: https://ropeblogi.wordpress.com/2016/05/25/religious-tenets-for-clerics/
