Development of nuclear data application softwarewith “Webble World”

Nuclear reaction data is applicable and considerably
important for public societies and various academic
communities, e.g., nuclear engineering, radiation therapy, and physics. Moreover, there exists a need formeans to utilize this data eﬃciently and conveniently
by individual users. To realize a system capable of utilizing such nuclear data, we are developing application
software.
There are several open tools available for searching
through data. However, these tools are versatile, andnot optimized for individual users. It is diﬃcult to satisfy both universality and optimization of the tools simultaneously. Under such situations, we are motivatedto create a tool customizable by “users”. In Hokkaido
University Meme Media Laboratory, the IntelligentPad(IP) system has been developed to circulate and manage the knowledge of information1) . On the IP system,
data and functions are treated as objects, which arecalled “Pads”. Since Pads can be connected to eachother, user can combine required Pads and constructs
original tools for the suitable to their needs.
In the previous work, we developed a“Nuclear Reaction Data and Handling Tools for the NRDF ”2–5) andthe “ Charged particle nuclear reaction data retrieval
system (CONTIP) ”4,5) . Here in, we plan to introduce“Webble World” to develop the current systems on theWeb. If the system can be extended through Webble
World, it will be independent of operating systems; it
is available through the Internet and can be shared between users. The users can customize and construct anoriginal tool for their own purposes.
The fundamental idea of Webble World is same asthat of the IP system. In the Webble World, an object
with a function is called a “Webble” (Fig.1), instead ofa “Pad”. Webbles connected by users are conserved in
the Webble World, and they are used as components
for a new Webble. Webble has some slots to connect
with others. For instance, if we connect an appropriate
slot in the “Text Webble” with the corresponding slot
in the “Display Webble” correctly, we can send thetext from the former Webble to the latter and viewthe text on the latter. A user, however, needs to know
the basic structure detail of a Webble, which is part of
the tasks in the development of a Webble tool.
The proposed new system can be utilized to search,
retrieve, and plot nuclear data. As objectives, anappropriate connection between the system and a
database and also the plot of the retrieved data arenecessary. There have already been Webbles with func∗1∗2

tions for the purposes as shown in Fig.2. The proposedsystem is slightly diﬃculty in terms of intuitiveness.
Therefore, we plan to develop simple usage manual toassist in developing the tools, while also considering
the needs of nuclear data users.
Hokkaido University Nuclear Data Centre (JCPRG)
is developing the system for using nuclear data with
Webble World. Work on making set of Webbles forsearching nuclear data, and manuals to use these compound Webbles, is progressing. In addition, we areconstructing a new data format using XML in order toimprove the usability7 of the system.
