DAML+OIL for Application Developers - slide "Content Negotiation"

content negotiation is an HTTP feature that allows clients to indicate the data formats they accept and prefer
a server might provide the same information in HTML, XML, and DAML+OIL formats
content negotiation is based on MIME Media types
we haven't yet established a MIME type for DAML+OIL, pending the decision on a MIME type for RDF
the client supplies an HTTP header indicating the MIME types it will accept in preferred order, e.g. Accept: image/gif, image/jpeg, */*
many HTTP servers calculate MIME types from file extensions
- e.g. .html and/or .htm result in text/html, etc.
we generally recommend that DAML URIs omit the trailing .daml to allow for content negotiation
most sites currently use text/plain for .daml to allow viewing by humans
until things settle down, we may sometimes need to use the trailing .daml to differentiate representations
