# OAI-PMH CONFIGURATION ![](/files/-MjA9Pr-zTz8hmn6CKd7) \ **OAI-PMH** It focuses on the transmission of metadata on any material in electronic support, being an essential requirement that these are encoded in **Dublin Core**. The **OAI-PMH** Protocol has the following characteristics: * How it works is based on a client-server architecture in which a metadata collection service requests information from a data provider. * Requests are expressed in HTTP, using only **GET** or **POST** methods. * All responses must be well-formed XML documents encoded in UTF-8. * Dates and time are encoded using ISO 8601 and expressed in UTC. * Supports the dissemination of logs in various metadata formats. * It has flow control. When there is an error or exception, repositories should indicate them by distinguishing them from HTTP status codes by including one or more error items in the response. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
