With the accelerated promotion of digital transformation of intangible cultural heritage, the sharing and dissemination of its intelligent data resources have become a key path to promote cultural inheritance and innovation. However, currently there is a widespread phenomenon of fragmented services and data silos in digital sharing platforms for intangible cultural heritage, which leads to low efficiency in resource sharing and seriously affects dissemination efficiency. In this regard, the concept of service design is introduced to construct a three-dimensional collaborative model of "technology-service-user", aiming to break the disconnection between technology and service, and establish a user centered intelligent data resource sharing platform for intangible cultural heritage. The service target groups are segmented through user profiling technology, the platform information architecture is optimized, the universal, inclusive, and sustainable design strategies are proposed, and the smart service design standards for international dissemination are developed. A sustainable development strategy for the intelligent data resource service platform of intangible cultural heritage is also put forward, including the construction of an intangible cultural heritage design ecosystem, the use of immersive experience technology, and the introduction of innovative methods such as crowdsourcing design patterns. By constructing quantifiable service design standards (Including 5 major categories), theoretical support and practical guidance have been provided for the efficient utilization and widespread dissemination of intelligent data resources for intangible cultural heritage, promoting the long-term development of intelligent services for intangible cultural heritage.
