AbstractIIS-9817444Buneman, Peter University of Pennsylvania$174,951DLI Phase 2 - DATA PROVENANCE This project will address issues associated with data provenance. Provenance is concerned with how information has arrived at the form in which appears -who produced it, who has corrected it, how old it is, it was originally produced, and so forth . Understanding provenance has occupied scientists, historians, textual critics and other scholars for centuries.The provenance of data in databases is a newer and larger problem, because one is interested in data at all levels of granularity - from a single pixel in a digital image to a whole database. Just as scholars comment on documents by attaching annotations (marginalia) to text, part of the solution to recording provenance is the attachment of annotations to components of databases. Database researchers have recently consideredloosely structured forms of data and have developed software systems for querying and storing such data. This work is closely related to new formats that have been developed for structured documents on the Web. It is expected that this technology will provide the substrate for recording and tracking provenance by advancing new data models, new query languages and new storage techniques.

摘要IIS-9817444 Buneman，彼得宾夕法尼亚大学$174，951 DLI第2阶段-数据来源本项目将解决与数据来源相关的问题。出处与信息是如何到达出现的形式有关-谁产生了它，谁纠正了它，它有多古老， 它是最初生产的，等等。 几个世纪以来，科学家、历史学家、文本评论家和其他学者一直在研究数据的出处。数据库中数据的出处是一个更新、更大的问题，因为人们对所有粒度级别的数据都感兴趣--从数字图像中的单个像素到整个数据库。 正如学者通过在文本中附加注释（旁注）来评论文档一样，记录出处的部分解决方案是将注释附加到数据库的组件上。 数据库研究人员最近考虑了松散结构的数据形式，并开发了用于查询和存储此类数据的软件系统。这项工作与为网上结构化文件开发的新格式密切相关。 预计这项技术将通过推进新的数据模型、新的查询语言和新的存储技术，为记录和跟踪出处提供基础。
