Diese Komponente entspricht also den BufferMetadata im LocalBufferStage: es ist ein technischer Implementierungs-Service, auf dessen Basis das BufferStore-API durch Abstraktion realisiert werden kann

in Ticket #1366 (und auch oben in der Mindmap) habe ich definiert, wie ein gutes Framework aussehen sollte. Aber das ist mehr eine Wunschliste &#8212; was gebraucht w&#252;rde w&#228;re ein Satz koh&#228;renter Concepts, denn es geht grade <i>nicht</i>&#160;darum, eine einzige &#187;Library-Implementierung&#171; zu schaffen; vielmehr geht es darum, die diversen Library-Container und Frameworks so unter einen Hut zu bekommen, da&#223; sie <i>composable</i>&#160;werden.

Das erscheint bereits elaboriert genug, um damit eine echte Render-Engine zu betreiben. Wobei festzuhalten ist, da&#223; das genze Konzept mit den hierarchiscen Metadaten bisher eine &#187;frei drehende Idee&#171; ist, und einer gr&#252;ndlichen Kritik unterzogen werden sollte.
