Indonesia has a wealth of traditional knowledge that is very diverse. However, this traditional knowledge is known by the local community who has such knowledge, so that it can not be controlled and monitored by the location of its distribution. So also what data is collected, the data processing flow and the organization that has the data is not known clearly. In addition, digitalization data of traditional knowledge is dispersed and stored in stand-alone systems. Therefore, data integration is needed to avoid duplication of traditional knowledge data. This study aims to analyze the situation and problem of digitalization of traditional knowledge in Indonesia and propose a model and architecture of web-based GIS distribution of traditional knowledge in Indonesia. Contribution in this research is try to combine approach used in this research is soft system methodology (SSM) and service-oriented architecture (SOA) approach to build web-based GIS and give recommendation of web-based GIS model of traditional knowledge in Indonesia.
