  description: "The service information (SI) document holds a definition of services provided by the service provider (e.g. MetaPub), including any relevant metadata and bearer details, such as:\n\n* Names\n* Descriptions\n* Logos\n* Bearers (broadcast and IP)\n\nMetaPub provides two SI documents. The _National SI document_ describes the distribution services provided by PRSS including basic service metadata, logos, and bearers. The current design defines two IP based services, although this may change in the future:\n\n* Streams\n    * Bearer ID: prss:streams\n    * Service ID: streams\n* Files\n    * Bearer ID: prss:files\n    * Service ID: files\n\nThe _Station SI document_ describes the stations and broadcast services served by PRSS. Only stations and broadcast services that have opted into metadata publishing are listed in this document.\n\nBased on [ETSI TS 102 818 v3.4.1](https://www.etsi.org/deliver/etsi_ts/102800_102899/102818/03.04.01_60/ts_102818v030401p.pdf) section 10.2.4, the SI document will be placed in a defined location on the service website. Using standard HTTP cache mechanisms, the SI document will only need to be fetched and processed occasionally.\n\nThe response will use standard HTTP cache-control headers to indicate when the document should be refreshed as well as an ETag to allow for lightweight change detection.\n"
