        Jeff Young develops Extensible Repository Resource Locators (ERRoLs) for OAI Identifiers
        OCLC Researcher Jeff Young has developed a scheme for creating "Cool" (i.e., unchanging) URLs for metadata, content, and services related to registered Open Archive Initiative (OAI) repositories.

        <P>Anyone can create or use a Cool URL to any metadata record or web resource related to supported OAI repositories.&nbsp; Similarly, any OAI repository can use the ERRoL service by registering a unique repository identifier with the OAI Registry at UIUC.</P>
    <P>An ERRol resolver is a system that uses a repository’s unique identifier to create URLs that point to metadata and content stored in the repository.</P>
    <P>Services that accompany ERRoLs include customizable HTML views of repositories, RSS feeds of OAI content, OAI-PMH version transformations, and OAI record unwrapping (i.e. providing "Cool" URLs to XML content in OAI repositories w/o the OAI wrappers).</P>
    <P>Other services are planned such as record editing, metadata crosswalks, and content resolution as well as integration of user defined services.</P>
