# Data Source Attachments Documents from your organization can be associated with features or records of a spatial or non-spatial data source. This is done through layers and tables configured from the data source in projects published via JMap NG applications. Depending on their permissions, JMap NG application users can: * View documents in tooltips (if you have configured the tooltip content to show them) and forms. * Attach or delete documents, or modify their metadata, from the layer or table form. The permissions for the data source's features or records apply to the attached documents. Documents have the following metadata: * File name * Date added * Name of the user who added it * Description * Subject Documents added together share the same description and subject. The subject is used to group documents when they are displayed in tooltips or forms. A wide variety of document formats can be attached to the data source (images, Word, PDF, URL, etc.). Documents are displayed in tooltips and forms. Images are displayed in separate tooltips. A single document can be attached to multiple features or records. --- # 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.
