过去一段时期，公共数字文化资源建设注重资源组织和整合，现阶段其重心从“藏”转向于“用”，着重于“用户体验”及“文化服务”。文章以馆藏唐三彩数字文化资源为对象，综合运用用户画像和扎根理论，在用户角色建构基础上对馆藏唐三彩数字文化资源展示的语义需求逐级编码，建构了馆藏唐三彩数字文化资源展示的语义描述模型，从标识描述、基本描述、价值描述以及延伸描述四方面揭示了馆藏唐三彩数字文化资源展示语义描述的核心需求，最终据此制定了馆藏唐三彩数字文化资源展示的元数据框架。

In past decades, great attention has been paid to organization and integration in public digital cultural resources, but now the main work transfers from storage to utilization, focusing on user experience and cultural service. Taking Tang Tri-color as the object, based on user's portrait and Grounded Theory, this study builds up specific personal requirements and encodes their different semantic requirements on the display of Tang Tri-color. Then it constructs a semantic description model, showing the core need of semantic description on digital cultural resources from all aspects including identification description, basic description, value description and extended description. Relying on the preceding steps, the metadata framework on display of Tang Tri-color resources is established.
