System Reference Document
open-in-new
<p>In the <a href="/facts/Open_gaming/SSVVJvqc">open gaming</a> movement, a System Reference Document (SRD) is a reference for a <a href="/facts/Role-playing_game/bN0QjhPs">role-playing game</a>'s mechanics licensed under a <a href="/facts/Public_copyright_license/uA15yXba">public copyright license</a> to allow other publishers to make material compatible with that game. In 2000, <a href="/facts/Wizards_of_the_Coast/QNYRhAT8">Wizards of the Coast</a> pioneered this by releasing a SRD for <a href="/facts/Dungeons_%2526_Dragons_3rd_edition/zBMbxaUC"><i>Dungeons & Dragons</i> 3rd edition</a> under their <a href="/facts/Open_Game_License/vwRY5Qwu">Open Game License</a> (OGL). </p><p><i><a href="/facts/Dicebreaker/SW2goULD">Dicebreaker</a></i> described a SRD as a "handy guide on how to use, hack and implement an existing game system for your own purposes". </p>
