View function of KEKB operation log system (Zlog)

Zlog system, an operational logbook system based on Zope, has been used at the KEKB and PF-AR accelerator facilities for 4 years. Because of the flexible structure and extensibility of Zope, Zlog system has been introduced in several projects such as J-PARC, RI-beam of RIKEN. And it has been planning at VEPP-5 accelerator. There have been established two ways as how to display images on Zlog system conventionally. One structure to handle image objects put on other places in the Zope installed OS as Zope objects. As another structure, we separately have a picture directory, which are served through other web server. We needed different Zlog of the structure. We expand function corresponding to both structures. And We added a function to refer the arbitrary image file URL. We expanded the text display function to cope some language. This report shows present status and recent development of Zlog system view functions. (author)
