Dear Gentleman, In april 2002 the metalife team released the first version of the metalife explorer. with metalife explorer the next central metalife tool is implemented in a first version. It enables the user to access the content of metalife knowledgebase thoroughly. All integrated data sources are exploited with one query. Simple queries as well as advanced queries are possible. The user does not need to know the internal data structures of the different data sources. Cross database queries are possible. A compact yet comprehensive dossier about a gene or a protein can be obtained with a single query. Data obtained from structured databases stand in line with text extracted data. Among others, information of the dossiers includes sequences, pathways, publications, patents and relation to diseases. metalife explorer serves as a core part of the metalife working environment. best regards your Metateam
