Design and implementation of ecological data collection management software based on DOI mechanism

Abstract

The Three-River Source region is located at a high altitude in the hinterland of the Tibetan Plateau, the complexity of the region and its biodiversity make its ecological data of the region very invaluable. In order to realize data sharing and further processing of the Three-River Source’s ecological data, it is essential to formulate a unified data collection and management standard for ecological data. In the paper, a method based on DOI mechanism for ecological data collection and management of the Three-River Source is proposed, and the corresponding software model is implemented and verified. Specifically, for the collection and transmission of ecological data, the metadata-based data collection model and a TCP/IP protocol-based data transmission structure are adopted to ensure the effectiveness, integrity and availability of ecological data collection and transmission between different sites. In respect of data management and storage, the data identification method based on the Digital Object Unique Identifier (DOI) is adopted in the software, meanwhile MySQL is used to realize the storage of descriptive information under DOI flag data, so as to realize the efficient management of multi-source ecological data, as well as improve the accuracy of data retrieval by users. Through testing results, the specific software model implemented based on the design scheme proposed in the paper is consistent with the expected results and can meet the requirements.
