XML and the Future

1998: XML 1.0

• SGML and XML are the only 2 real MLs.
• They are the real languages ("Metalanguages").
• Other "MLs" are instances based on a DTD.

Is SGML dead?

• XML is SGML; think of it as SGML--.
• Some powerful but difficult facilities omitted.
• Optional features omitted.
• See Goldfarb's sgmlsource.com for an indication of SGML's future.

XML: Documents and Data

• Document and content management
• Database management (vs. RDBMS)
• RPC mechanisms (vs. DCOM, Corba, JNI)
