Much of the essential metadata needed for full resource discover has been defined and presented in the Standards LINK section of OAWAL. The most important elements for consideration are:

• Digital Object Identifiers (DOIs): Many librarians register DOIs for newly presented open access content but where librarians fall short in their repositories is with the assignment or relationship development between pre-print content and fully published articles on commercial web sites. In order to show relationship between the pre-print and the fully published article, it is advised that the full published DOI be added as metadata to your repository record for any pre-print or post-print article.
• ORCID: While ORCID is seen as a way to associate all relevant content with a single author/researcher, there are concerns within the library community that authors/researchers are often applying for multiple ORCIDs upon publication. Currently, there is not a clear way to associate all ORCIDs an author/researcher may have to one another. Until this occurs, there is still plenty of opportunity for the ambiguity of authorship to occur.
• I² (Institutional Identifiers): I² or the Institutional Identifier is seen as a very relevant and often vital missing piece of metadata not used by many repositories. As it is being picked up and used by more and more commercial publishers, it is strongly recommended that repository managers become familiar will all the variant institutional identifiers used by their institution and applies this metadata to content loaded into the repository.
• FundRef : is just beginning to be utilized readily by both the commercial publishers and by many of the alternative metrics providers as additional metadata regarding article production. This standard is extremely important to researchers in particular because it gives clear indication of what types of research are funded by what research councils/bodies. This is also a key metadata element needed by the research offices at many institutions for complete funding compliance, especially when the funding body dictates the eventual open access publication of the research funded. While there has been a concerted effort to encourage the commercial publishers to use this standard, there has not been the same emphasis applied to repositories and for repository managers.
• CrossMark: is another standard that has not been utilized or widely adopted by repositories or repository managers for utilization. Since CrossMark is intended to indicate the version of an article, it makes perfect sense to be utilized in the repository setting as well as on commercial publishing sites.
