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=4ec9bec6bf35fd2f1a58a4be7f5ec64a02174nas a2200205   4500008004100000245005800041210005800099260000900157300001200166490000600178520153100184653001301715653002401728653003101752653002501783100001501808700001301823700001501836856011701851       2007                        eng d00aEmergent semantics in personalized multimedia content0 aEmergent semantics in personalized multimedia content  c2007  a55 - 600 v53 aAuthoring of personalized multimedia content can be considered as a process consisting of selecting, composing; and assembling media elements into coherent multimedia presentations that meet the user's or user group's preferences, interests, current situation, and environment. In the approaches we find today, media items and semantically rich metadata information are used for the selection and composition task. However, most valuable semantics for the media elements and the resulting multimedia content that emerge with and in the authoring process are not considered any further. This means that the effort for semantically enriching media content comes to a sudden halt in the created multimedia document - which is very unfortunate. In this paper, we propose with the SemanticMM4U framework an integrated approach for deriving and exploiting multimedia semantics that arise with and from the creation of personalized multimedia content and make it available for further use and applications. In this approach, not only the metadata are considered that are semantically evolving from the media elements of the newly created presentation. Also the actual usage of media elements for the authoring can emerge new semantics of the single media elements employed. In the application domain of authoring of digital photo albums we show where and how semantics emerge in the authoring process and how these contribute to an even richer media content pool, both for single media and also for the composition and its later use.10aMetadata10aMultimedia elements10aMultimedia personalization10aMultimedia semantics1 aScherp, A.1 aBoll, S.1 aCremer, H.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-37849008165&partnerID=40&md5=366f71c39eca694096c9135c18c67f12
