论文摘要
IVOA出处数据模型将实体，代理和活动定义为容器类，以描述数据集的出处，并附有执行的任务和职责。它还提供了一组类来描述活动类型及其配置模板，以及在执行任务期间有效应用的配置。在这里，我们重点介绍了在HST髋关节数据收集的CDS Provhips Service分发出处元数据以及用于生产臀部瓷砖的HST档案原始图像中所学到的经验教训。节目基于Provatap协议，该协议是用于分发出处元数据的新兴TAP标准。普罗维塔普查询可能会迅速变得非常复杂。已经考虑了各种图形表示策略，包括临时解决方案，Triplestore和SQL CTE，并很快被讨论。
The IVOA Provenance Data model defines entities, agents and activities as container classes to describe the provenance of datasets, with the executed tasks and responsibilities attached to agents. It also provides a set of classes to describe the activities type and their configuration template, as well as the configuration applied effectively during the execution of a task. Here we highlight lessons learned in the implementation of the CDS ProvHiPS service distributing provenance metadata for the HST HiPS data collections, and for the HST archive original images used to produce the HiPS tiles. ProvHiPS is based on the ProvTAP protocol, the emerging TAP standard for distributing provenance metadata. ProvTAP queries may rapidly become very complex. Various graph representation strategies, including ad hoc solutions, triplestore and SQL CTE have been considered and are discussed shortly.
