The Maintenance Operation Protocol (MOP) is used for utility services such as uploading and downloading system software, remote testing and problem diagnosis. It was a proprietary protocol of Digital Equipment Corporation. MOP frames can be one of the following commands:
Operations, administration, and management or operations, administration, and maintenance (OA&M or OAM) are the processes, activities, tools, and standards involved with operating, administering, managing and maintaining any system. This commonly applies to telecommunication, computer networks, and computer hardware. In particular, Ethernet operations, administration and maintenance (EOAM) is the protocol for installing, monitoring and troubleshooting Ethernet metropolitan area network (MANs) and Ethernet WANs. The OAM features covered by this protocol are discovery, link monitoring, remote fault detection and remote loopback.
WebDAV (Web Distributed Authoring and Versioning) is a set of extensions to the Hypertext Transfer Protocol (HTTP) allowing user agents to collaboratively edit content directly in an HTTP server, which may act as a file server. It provides facilities for concurrency control and namespace operations, thus allowing the Web to be viewed as a writeable medium and not just a read-only medium. WebDAV is defined in RFC 4918 by a working group of the Internet Engineering Task Force (IETF). The WebDAV protocol provides a framework for users to create, change and move documents on a server. The most important features include the maintenance of properties about an author or modification date, namespace management, collections, and overwrite protection. Maintenance of properties includes such things as the creation, removal, and querying of file information. Namespace management deals with the ability to copy and move web pages within a server's namespace. Collections deal with the creation, removal, and listing of various resources. Lastly, overwrite protection handles aspects related to the locking of files. It takes advantage of existing technologies such as Transport Layer Security, digest access authentication or XML to satisfy those requirements. Modern operating systems such as GNOME Desktop Environment for Linux provide built-in client-side support for WebDAV.
The Protocol on Ireland/Northern Ireland, commonly abbreviated to the Northern Ireland Protocol (NIP), is a protocol to the Brexit withdrawal agreement that sets out Northern Ireland’s post-Brexit relationship with both the EU and Great Britain. The Withdrawal Agreement, including the Protocol, came into effect on 1 January 2021. Citing the island of Ireland's "unique circumstances", the Protocol governs unique arrangements on the island between the United Kingdom and the European Union; it regulates some aspects of trade in goods between Northern Ireland and the rest of the United Kingdom. The Protocol's arrangements, under which Northern Ireland but not the rest of the UK remains in the EU single market for goods, allow the maintenance of the open border between Northern Ireland and the Republic of Ireland. The establishment of the open border was a key aspect of the Northern Ireland Peace Process and Good Friday Agreement which ended the Northern Ireland Conflict. The Protocol instead creates a de facto customs border in the Irish Sea between Northern Ireland and Great Britain. Principally to address concerns of Ulster Unionists about the Protocol, in 2022-23 the EU and UK agreed revised arrangements for its operation – the Windsor Framework – which took effect on 24 March 2023. The Democratic Unionist Party declined to accept the Framework as meeting their concerns until further adjustments to its operation were agreed on 31 January 2024 and the formation of a new Northern Ireland Executive began.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
