MNN Future Directions

In this release of MNN, Netscape has intentionally limited the complexity of the RSS format. However, in the future, Netscape plans to work with other organizations to enhance the RSS format to support additional tags, while making it more compliant with existing W3C standards for XML and RDF.

For example, as shown in Figure 1, Netscape is planning to enhance RSS to support a variety of new features. Such features include a richer metadata description, for more powerful searching and personalization capabilities, subchannels, related channel information, keyword-based collection of data, direct referencing of other RDF structures, PICS ratings, and more.

Please send your comments and suggestions to mnn_feedback@netscape.com.
