Organizing medical networked information (OMNI).

The Internet has become a major source of biomedical information over the last 5 years. Several projects have recently been established to help users find respectable information sources quickly. OMNI (Organizing Medical Networked Information) is one such filtering and indexing project. OMNI has focused on the quality of information and the application to Internet resources of standard tools for organizing information such as the National Library of Medicine's Medical Subject Headings and the Dublin Core metadata format. Now two years old, the OMNI project fulfils a valuable role for the UK biomedical community, through its gateway service (http:@omni.ac.uk), its printed resource guides and its training workshop programme. OMNI is also a focus for biomedical metadata activities in the UK. The gateway continues to grow in size and further work on information quality issues and integration is planned.
