UMBEL\'s first 11 semantic Web services and online demos show how a lightweight structure of 21000 subject concepts can provide context for inter-linking external data and ontologies. Additional value through the network effect of inherited relationships and properties is also gained as more structure and data is added. UMBEL is an excellent upper mapping and binding layer for integrating Linked Data and rich sources of named entities such as Wikipedia. The UMBEL subject concepts are derived from the OpenCyc version of the proven Cyc knowledge base.
