The article presents the author’s view of some of the reasons that have so far kept the framework of Functional Sentence Perspective (FSP) from becoming a descriptive part of modern computerized language corpora. Drawing on the historical development of the various FSP tagging systems used by the key contributors to the Brno approach of FSP, namely professors Jan Firbas and Aleš Svoboda, the author presents a unified subset of FSP tags, called The CD Subset and forming a part of a recently proposed new FSP tagging scheme, to foster the construction of a computerized corpus containing language data annotated on the level of FSP.
