论文摘要
就像网络上的任何其他资源一样，学术资源可能会参考腐烂，因为它们经常消失或随着时间的流逝而显着变化。数字对象标识符（DOIS）是持续识别学术资源并已成为引用它们的事实上标准的司空见惯。我们通过分析其在网络上的解决方案来研究DOI的持久性概念。我们对这些标识符的持久性获得了信心，部分原因是，无论我们使用哪种HTTP请求方法或我们从哪个网络环境发送我们发送请求的网络环境，DOI都将始终如一地返回相同的响应。但是，我们的实验表明，根据我们的解释，持久性并不保证。我们发现，学术内容提供者对不同的请求方法和网络环境的反应不同，甚至改变了他们对同一DOI请求的反应。在本文中，我们介绍了我们的定量分析结果，旨在告知学术传播社区这种令人不安的缺乏一致性。
Scholarly resources, just like any other resources on the web, are subject to reference rot as they frequently disappear or significantly change over time. Digital Object Identifiers (DOIs) are commonplace to persistently identify scholarly resources and have become the de facto standard for citing them. We investigate the notion of persistence of DOIs by analyzing their resolution on the web. We derive confidence in the persistence of these identifiers in part from the assumption that dereferencing a DOI will consistently return the same response, regardless of which HTTP request method we use or from which network environment we send the requests. Our experiments show, however, that persistence, according to our interpretation, is not warranted. We find that scholarly content providers respond differently to varying request methods and network environments and even change their response to requests against the same DOI. In this paper we present the results of our quantitative analysis that is aimed at informing the scholarly communication community about this disconcerting lack of consistency.
