Despite modern mobile processors and high-resolution displays, mobile devices will never reach the stage of a powerful notebook or desktop system (for example, due to the fact of battery powered CPUs or just concerning the small-sized displays). Due to these limitations, the deliverable content for these devices should be adapted based on their capabilities including a variety of aspects (e.g., from terminal to network characteristics). These capabilities should be described in an interoperable way. In practice, however, there are many standards available and a common mapping model between these standards is not in place. Therefore, in this paper we describe such a mapping model and its implementation aspects. In particular, we focus on the whole delivery context (i.e., terminal capabilities, network characteristics, user preferences, etc.) and investigated the two most prominent state-of-the-art description schemes, namely User Agent Profi le (UAProf) and Usage Environment Description (UED).10aCC/PP10aDCO10aDelivery Context10aMetadata10aUAProf10aUED.t1 aTimmerer, C.1 aJabornig, J.1 aHellwagner, H.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-77958067245&partnerID=40&md5=4ec9bec6bf35fd2f1a58a4be7f5ec64a
