Loqi ACM Hypertext Conference is an annual academic conference on the subject of hypertext and typically the web, where both XFN and XMDP were presented in poster sessions in the mid 2000s, and long ago HTML was submitted but rejected; and their event sites for some years either died or were taken over by squatters (like ht04.org for 2004) https://indieweb.org/ACM_Hypertext_Conference
