This section will describe what it means for research to be accessible
(Meta)data are retrievable by their identifier using a standardized communications protocol:
Simply put, it’s an access method of exchanging data over a computer network. Each protocol has its rules for how data is formatted, compressed, checked for errors. Research repositories often use the OAI-PMH or REST API protocols to interface with data in the repository. The following image from TutorialEdge.net: What is a RESTful API by Elliot Forbes provides a useful overview of how RESTful interfaces work:
Hydroshare offers a REST API protocol which will enable many of the functions that are accessible through the web user interface, to be done programmatically:
Wikipedia has a list of commonly used network protocols but check the service you are using for documentation on the protocols it uses and whether it corresponds with the FAIR Principles. For instance, see Hydroshare’s API Instructions page.
Alternatively, for sensitive/protected data, if the protocol cannot guarantee secure access, an e-mail or other contact information of a person/data manager should be provided, via the metadata, with whom access to the data can be discussed. The DataCite metadata schema includes contributor type and name as fields where contact information is included. Collaborative projects such as THOR, FREYA, and ODIN are working towards improving the interoperability and exchange of metadata such as contributor information.
Across the research ecosystem, publishers, repositories, funders, research information systems, have recognized the need to address the problem of author disambiguation. The illustrative example below of the many variations of the name Jens Åge Smærup Sørensen demonstrations the challenge of wrangling the correct name for each individual author or contributor:
Thankfully, a number of research systems are now integrating ORCID into their authentication systems. Zenodo provides the login ORCID authentication option. Once logged in, your ORCID will be assigned to your authored and deposited works.

Exercise: ORCID and Accessibility
ORCID features a principles page where we can assess where it lies on the spectrum of these criteria. Can you identify statements that speak to these conditions: open, free, and universally implemetable?
There are a variety of reasons why a placeholder with metadata or tombstone of the removed research object exists including but not limited to staff removal, spam, request from owner, data center does not exist is still, etc. A tombstone page is needed when data and software is no longer accessible. A tombstone page communicates that the record is gone, why it is gone, and in case you really must know, there is a copy of the metadata for the record. A tombstone page should include: DOI, date of deaccession, reason for deaccession, message explaining the data center’s policies, and a message that a copy of the metadata is kept for record keeping purposes as well as checksums of the files.
DataCite offers statistics where the failure to resolve DOIs after a certain number of attempts is reported (see DataCite statistics support pagefor more information). In the case of Zenodo and the GitHub issue above, the hidden field reveals thousands of records that are a result of spam.
If a DOI is no longer available and the data center does not have the resources to create a tombstone page, DataCite provides a generic tombstone page.
See the following tombstone examples:
