SDCI Data New: Trust Management for Open Collaborative Information Repositories: The CalSWIM CyberinfrastructureCristina Videira Lopes (PI), Michael Goodrich (co-PI), and Stanley Grant (co-PI) of University of California, Irvine, with Roberto Tamassia (subcontractor) of Brown UniversityThe California Sustainable Watershed Information Manager (CalSWIM: http://calswim.org) is a cyberinfrastructure supporting the dissemination and analysis of watershed information in Southern California. CalSWIM provides watershed stakeholders ? scientists, regulators, and the general public ? access to stream monitoring data and relevant GIS geospatial data, and the ability to analyze data with modeling tools of varying sophistication. Like so many other scientific cyberinfrastructures, the CalSWIM web site has been a closed infrastructure, i.e. its update has been controlled by a small number of individuals, and any changes to it require the intervention of web-knowledgeable professionals. This model does not scale to the ambition of the CalSWIM project. In order to make this cyberinfrastructure sustainable, expandable, outreaching, and continually up-to-date, we are currently transforming CalSWIM into an Open Collaborative Information Repository, in the form of a wiki with advanced content management features, including databases, GIS layers, and other forms of digital data. By opening CalSWIM in a wiki manner, we empower the domain experts to update the site directly, without requiring them to have web programming knowledge. We also provide a framework for engaging the general public in the process, therefore benefiting from the public's critical supervision of the content, and from valuable volunteer contributions that cannot occur in a closed infrastructure. The current work aims at creating a publicly updatable encyclopedia of ?all things watershed? that includes all watersheds in California. Open information infrastructures such as the one we are developing are sometimes met with skepticism from their users. The chaotic nature of Wikipedia ? one the most visible collaborative information repositories ? will not be appropriate for open cyberinfrastructures supporting collaboration over scientific and regulatory information. The CalSWIM wiki will only succeed if issues of trust are taken into consideration in its design. Trust is a complex concept based on personal and social factors, that includes assurances about data security, knowledge about data provenance, knowledge about authors' reputations, and assurances about author attribution (citations and quotations) in uncontrolled contexts. This project will design, develop, and deploy a trust layer on top of open information repositories, such as the CalSWIM wiki, that will minimize the existence of poor-quality information and also minimize the effect of malicious information manipulation. Our approach is based on a mixture of access control systems, reputation management systems, and data integrity algorithms. More specifically, the outputs of this project will be: (1) A new trust management model specifically designed to address the needs of collaborative scientific and regulatory information repositories, where the addition of data and the creation of data analyses is open to scientists, regulatory agencies, interest groups, and the general public. This trust model will be implemented as a software package, and it will be made publicly available as open source. (2) A new method and visualization system for ensuring the integrity of data used (i.e., ?quoted?) in uncontrolled contexts based on cryptographic hash functions and prooflets. (3) A concrete deployment of the previous two items in one specific cyberinfrastructure, CalSWIM, along with an assessment of how effective they are in managing trust.Although the CalSWIM wiki is the concrete cyberinfrastructure on which this trust management component will be deployed, the trust management component developed in this project can be applied to a variety of Collaborative Information Repositories that share the properties of CalSWIM ? namely, data-based collaboration between scientists, regulatory agencies, and the general public. We will disseminate the results of this project and make it widely available to other groups by using the open source model and by making an outreach effort to those organizations that could benefit from adopting this model.

SDCI数据新：开放协作信息存储库的信任管理：Calswim Cyber​​infrastrstructurecristina videira lopes（PI）（PI），Michael Goodrich（Co-Pi）和加利福尼亚大学的Stanley Grant（Co-Pi），欧文分校，欧文分校，Irvine，Irvine，Irvine，Roberto tamassia（Roberto tamassia california california of Brownia of Brownia the Califers of Browniabliable of Brown of Browniable of Browniable of Brownia the Calieptia） http://calswim.org）是一种网络基础设施，支持南加州的流域信息的传播和分析。卡尔斯温提供流域利益相关者？科学家，监管机构和公众？访问流监视数据和相关的GIS地理空间数据，以及使用不同复杂的建模工具来分析数据的能力。像许多其他科学的网络基础设施一样，Calswim网站也是一个封闭的基础架构，即其更新受到少数个人的控制，并且任何更改都需要干预网络知名的专业人员。该模型并不扩展到Calswim项目的野心。为了使这种网络基础设施可持续，可扩展，推广并不断最新，我们目前以具有高级内容管理功能的Wiki的形式将Calswim转换为一个开放的协作信息存储库，包括数据库，GIS层，GIS层，GIS层和其他形式的数字数据。通过以Wiki的方式打开Calwesim，我们可以授权域专家直接更新站点，而无需他们拥有网络编程知识。我们还提供了一个框架，以使公众参与此过程，因此受益于公众对内容的关键监督，以及在封闭的基础设施中无法发生的宝贵志愿者捐款。当前的作品旨在创建一个分水岭的公共更新的百科全书？其中包括加利福尼亚州的所有流域。我们正在开发的开放信息基础架构有时会受到用户的怀疑。维基百科的混乱性？最明显的协作信息存储库之一？不适用于支持科学和法规信息协作的开放网络基础设施。只有在考虑其设计中考虑信任问题的情况下，Calswim Wiki才能成功。信任是一个基于个人和社会因素的复杂概念，其中包括有关数据安全性，有关数据出处的知识，有关作者声誉的知识以及在不受控制的上下文中对作者归因（引用和引文）的保证的知识。该项目将在开放信息存储库（例如Calswim Wiki）上设计，开发和部署一个信任层，这些信任层将最大程度地减少质量不佳的信息的存在，并最大程度地减少恶意信息操纵的效果。我们的方法基于访问控制系统，信誉管理系统和数据完整性算法的混合。更具体地说，该项目的产出将是：（1）一种新的信任管理模型，专门旨在满足协作性科学和监管信息存储库的需求，在此添加数据以及数据分析的创建向科学家，监管机构，利益集团，兴趣集团和公众开放。该信任模型将作为软件包实施，并将作为开源公开提供。 （2）一种新方法和可视化系统，用于确保基于加密哈希功能和证明的不受控制的上下文中使用的数据完整性（即？引用？）。 （3）在一个特定的网络基础设施中对前两项的具体部署，以及评估它们在管理信任方面的有效性。尽管卡斯维姆·维基（Calswim Wiki）是一种具体的网络基础设施，具体的网络基础设施将在该基础上进行此类信任管理组成部分，在该项目中所开发的信任管理组成部分，可以将属性用于各种信息，以使各种各样的属性属于各种信息。也就是说，科学家，监管机构和公众之间基于数据的合作。 我们将通过使用开源模型并向那些可以从采用该模型中受益的组织进行外展努力来传播该项目的结果，并通过使用开源模型并为其他团体广泛使用。
