 Digital Object Identifiers are PIDs for objects such as publications and datasets, but also physical objects. DOIs are resolved based on the [Handle System](https://www.handle.net/)to lead to the corresponding landing page and are assigned by members of the [International DOI Foundation](https://datascience.codata.org/articles/abstract/353/). Most well-recognised [DOI registration agencies](https://www.doi.org/the-community/existing-registration-agencies/) include [CrossRef](https://www.crossref.org/) for publications and [DataCite](https://datacite.org/) focusing on [datasets](https://doi.org/10.1109/COINFO.2009.66).
 
-A DOI consists of a character string divided into two parts by a slash. The prefix always starts with a `10.` and identifies the registrant, who retrieves a DOI from a DOI registration agency. Every registrant has its own unique prefix. The suffix identifies a specific object registered by a registrant via a registration agency.

Every registrant has its own unique prefix. The suffix identifies a specific object registered by a registrant via a registration agency.
 
 DOIs are most frequently displayed as an URL such as `https://doi.org/10.1000/182` and include a resolver as HTTP proxy server to redirect to the linked object. DOIs are standardised by the [International Organisation for Standardisation](https://www.iso.org/) (ISO) in [ISO 26324](https://www.iso.org/standard/43506.html).

 ROR does support parent-child hierarchies as well as lateral relationships between organisations. An example might include a university having a child organisation such as a research institute [German: Fakultät] and related organisations such as a university hospital. However, ROR focuses on fundamental affiliations and is not focused on all subdivisions of an organisations such as departments [German: Institut] as high-level institutional information is more stable.

-The Persistent Identifier for eResearch ([ePICs](https://www.pidconsortium.net/)) are based on the [Handle.Net Registry (HNR)](https://www.handle.net/) and are intended to be used for unpublished digital research objects. To this end, ePICs can be assigned at early stages of research to locate research data and may be used by various research data management or archiving systems. Upon publication of a dataset, the full research data can be linked via the ePIC, for example, in cases that include proprietary or sensitive information.

+ARK prefixes are centrally assigned on request by the ARK Alliance and can be resolved centrally on ...
+The single ARKs are assigned and managed by the single institutions on an own server. Other that DOIs, they are free of charge.
+An ARK usually has the form: `ark:12148/btv1b8449691v/f29` and can be combined with different ARK URI prefixes leading to different resolving servers.
+Attaching a `?` at the end of an ARK allows adding a structured description of the resource.
+Much [software](https://arks.org/resources/) is available to mint, store, resolve, interpret ARKs.
