Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.os.uk/os-downloads/products/transport-network-portfolio/os-mastermap-highways-network-fundamentals/os-mastermap-highways-network-overview/product-packaging.md). # Product packaging When a customer receives an order from the OS Data Hub, the product will be packaged with the following elements: ### **Data folder** The data folder will contain the GML, GeoPackage or vector tiles files which make up the ordered product. The data folder will have been compressed to `data.zip` to enable a single download of the product. Once this has been downloaded, the data.zip file will contain all the data files which make up the ordered product and these files will have been compressed using gzip. ### **Doc folder** For GML, the doc folder will contain a summary.gml file which will contain specific information about the customer order, including: * The order number * Query extent polygon(s) of the order * The order type: Full Supply or COU * For COU orders, the change-since date The doc folder will have been compressed to `doc.zip` to enable a single download of the associated documents. The GeoPackage and vector tiles formats will have the same folder structure, but will be available for Great Britain coverage only, so will not contain COU files. ### **Resources folder** The resources folder will contain the product’s [Feature Validation Data Set (FVDS)](/os-downloads/products/transport-network-portfolio/os-mastermap-highways-network-fundamentals/os-mastermap-highways-network-overview/feature-validation-data-set.md), and a [lookup table to the OS Open Roads product](/os-downloads/products/transport-network-portfolio/os-mastermap-highways-network-fundamentals/os-mastermap-highways-network-overview/os-open-roads-lookup-table.md). The folder will have been compressed to `resource.zip` to enable a single download of the resources; within the zipped folder, the contents will have been compressed. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.os.uk/os-downloads/products/transport-network-portfolio/os-mastermap-highways-network-fundamentals/os-mastermap-highways-network-overview/product-packaging.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
