In August 1908, a white mob attacked Springfield, Illinois’s Black community, destroying homes and businesses and lynching two Black men. National outrage over the violence helped spur the movement that created the NAACP the following year.

JSON-WSP is a web service protocol that uses JSON for service description, requests and responses.[1]
It is inspired from JSON-RPC, but the lack of a service description specification with documentation in JSON-RPC sparked the design of JSON-WSP.
The description format has the same purpose for JSON-WSP as Web Services Description Language (WSDL) has for SOAP or interface description language (IDL) for Common Object Request Broker Architecture (CORBA), which is to describe the types and methods used in a given service. It also describes inter-type relations (i.e. nested types) and defines which types are expected as method arguments and which types the user can expect to receive as method return values. Finally the description opens the possibility to add documentation on service, method, parameter and return levels.
Communication between clients and a JSON-WSP server is carried out using HTTP POST[2] requests and responses, with the JSON objects as data with the content-type application/json.[3]
JSON-WSP consists of four JSON object specifications:
| Specification | Description |
|---|---|
| description | Service description specification (like WSDL). This specification describes methods, method parameters, types and return types. It also supports user documentation on service, method and parameter levels. |
| request | Specification for JSON requests. It contains information about which method that is to be invoked and all the arguments for the method call. Arguments in the request must obey the parameter definition of the same method described in the corresponding JSON-WSP description. |
| response | Specification for JSON responses. The response object contains the result of a service method invocation. The return type must obey the defined return type of the same method in the corresponding JSON-WSP description. |
| fault | Specification for JSON fault responses. The fault object contains a fault code and a fault string. The fault information specifies whether the fault occurred on the client or server side. Depending on the server side service framework more detailed information can be extracted, i.e. the filename and line number where the fault occurred. |

The following is a list of web service protocols. BEEP – Blocks Extensible Exchange Protocol CTS – Canonical Text Services Protocol E-Business XML Hessian Internet Open Trading Protocol JSON-RPC JSON-WSP SOAP – outgrowth of XML-RPC, originally an acronym for Simple Object Access Protocol Universal Description, Discovery, and Integration (UDDI) WebSocket Web Processing Service (WPS) WSCL – Web Services Conversation Language WSFL – Web Services Flow Language (superseded by BPEL) XINS Standard Calling Convention – HTTP parameters in (GET/POST/HEAD), POX out XLANG – XLANG-Specification (superseded by BPEL) XML-RPC – XML Remote Procedure Call
JSON-RPC (JavaScript Object Notation-Remote Procedure Call) is a JSON-based wire protocol for remote procedure calls (RPC). It is similar to the XML-RPC protocol, defining only a few data types and commands. JSON-RPC allows for notifications (data sent to the server that does not require a response) and for multiple calls to be sent to the server which may be answered asynchronously. The JSON-RPC protocol is transport-independent and can be carried over many different data transport protocols, including file descriptor I/O, HTTP and TCP. It does not directly provide any support for authentication or authorization.

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.
