Last issue I left you with the tagline, "But what will that future directory look like?" At the recent European Identity Conference (EIC) Michael Schwartz, CEO of GLUU -- with help from Drummond Reed, co-chairman of two OASIS Technical Committees: XRI (Extensible Resource Identifier) and XDI (XRI Data Interchange) -- presented a workshop on "Directories & Federation." It was neither the so-called "LDAP model" of hierarchical, object-oriented directory, nor a standard Relational Database (RDBMS) model of data store.

Instead, Schwartz talked about the XRI/XDI model as the basis for the data we think of as being in a directory (identifiers and attributes).
