Seismic Metadata Standards And Management Of Construction

The development of the IT that changes with each passing day has promoted the informative process of global society, the importance of metadata technology also brings into relief gradually. Because of form many shapes and the type of seismic data, and data scatters, the means of data collection as well as the way stocked, managed and handled are also not identical, therefore hard to realize management and the unified search for various different type inspection data, also lack unified effective data management and share to issue rule. Therefore establishment is taking seismic metadata as the data of the unification of standard to share system, is built especially the metadata standardization of seismic field, and it is very urgent to creat seismic metadata to share data platform, at the same time also is when data shares in, break the traditional field of" data islet" make beneficial exploration.Earthquake metadata has described quality and the content of data set in earchquake information, other features, space reference, management way as well as the way of showing, it is helpful for maintenance, discovery, location, excavation, assessment and the understanding of earchquake data. Metadata model is the development of metadata standard.This paper has first introduced structure and the role of metadata and the concept of metadata, metadata standard work out the contents such as principle and basis. On this foundation, having again introduced metadata to build mould needs use UMLAnd XML Schema Some related knowledge. Combination national earchquake department has worked out the standard of earchquake metadata concerning the standard of metadata, and expands to form earchquake metadata content, combines the metadata of our country to use present situation, has founded earchquake information metadata management system, system has realized the function of earchquake metadata collection and inquiry etc. mainly. The final work for full text makes summary, and have pointed out the direction of the effort of next step.
