When copying and pasting data between applications using the operating system clipboard, the semantics of the transfered information is usually lost. Using Semantic Web technologies these semantics can be explicitly defined in a machine process-able way and therefore be preserved during the data transfer. In this paper we introduce SemClip, our implementation of a Semantic Clipboard that enables the exchange of semantically enriched data between desktop applications and show how such a clipboard can be used to copy and paste semantic annotations from Web pages to desktop applications.
