With many supported item types, you can share a variety of apps, maps, documents, and data on your hub sites. Get started by checking out what types of items you can share as open data. When you're ready, upload items if they aren't already a part of your ArcGIS Online organization.
Supported item types
The following items are supported items for ArcGIS Hub:
|Maps and Apps|
ArcGIS Hub does not currently support raster layers within map services.
The following data types are supported in ArcGIS Hub but do not have their own dataset page. Users can search for these items within a site and access them directly from the search results page. These items will not appear on opendata.arcgis.com:
- URLs—The registered URL will open in a new tab.
- Documents—Word and PowerPoint documents will download in the browser.
- CSV files greater than 5 MB—The file will download in the browser.
Improve data quality
To optimize the usability of your data in sites, it is important that your data be complete with an accessible title, description, attribute aliases, license, and tags.
- Title—For individual layers, change the title inArcGIS Online to be clear and informative. For layers within map or feature services, change the title locally, and publish the service with clean titles. ArcGIS Hub will remove any underscores in your title.
- Description—Change the description in ArcGIS Online. Layers within map or feature services will take the description of the entire service. If you do not enter a description, Hub will automatically provide Description not provided
- Field aliases—Change complex GIS data field names to a more user-friendly description of the content of the field. Dataset downloads will supply the field name, but not the field alias.
If you add a Creative Commons license (CC0, CC BY, CC BY-SA) by either the name or URL, the data's page will display the Creative Commons license icon and will link to the appropriate license details web page. If you add an Open Data Commons license (PDDL, ODbL, ODC-By), the dataset page will display the license name and link to the appropriate license details web page.
- Tags—Tags help users discover your datasets through searches. For individual layers, add tags in ArcGIS Online. All layers within map and feature services will have the same tags as set for the entire service in ArcGIS Online.
- Thumbnails—ArcGIS Online item thumbnails will appear beside the dataset in the search results. All layers within map and feature services will have the same thumbnail.
- Structured Metadata—Add official metadata files to the ArcGIS Online item and users can access it via ArcGIS Hub.
Hub downloads will change the data schema so that all values will be within the signed range of integer values that can be stored in 32 bits. This means that field lengths, field precision, and scale may be altered in the download. The data itself will not change.
Only the following HTML tags will be respected in the Description and License fields on Hub. Text in other tags will appear in-line: h3, h4, h5, h6, img, blockquote, p, a, ul, ol, nl, li, b, i, strong, em, strike, code, hr, br, div, table, thead, caption, tbody, tr, th, td, pre.
Services must be registered to ArcGIS Online to be added to ArcGIS Hub. When working with map and feature services, you can register services containing multiple layers, or register the individual layers themselves.
Register services with multiple layers
This is a quicker way of getting your data live, but it gives you less control over search results and an item's metadata. All layers within the service will have the same description and the same tags, and all layers will appear in search results when a tag or the service name is called.
Register individual layers
Individual layers provide greater control over the item's metadata—you can edit individual titles and descriptions within ArcGIS Online. Each layer will have different tags as set in ArcGIS Online, which will provide better search results for the end user.
To learn more about registering services and service configuration, see Server configuration details.
Add additional download files
All (vector) datasets are automatically available for download as CSV files, KML files, and shapefiles and accessible in the GeoJSON and GeoService APIs. You can add additional download files or related documents by adding custom distributions to the dataset's structured metadata. This is a good way to support CAD file download formats or file geodatabases for nonhosted feature services. Additional download files that you add in the metadata will appear as options in the download section of the dataset page on ArcGIS Hub.
To add additional download files, follow these steps:
- On the item page in the home application, click Metadata.
Note:If you do not see a metadata button, you must have an administrator enable metadata for your organization.
- On the metadata form, click Distribution.
- On the Online Resource page that appears, click the plus sign.
- Enter a URL to your download file or external related link.
- Enter a name for the file. This name will appear on ArcGIS Hub.
- Change the Function parameter to Download.
You can add as many additional download files as you want by repeating steps 3 through 6.
Entering additional distributions in the metadata will expose the entire metadata to the user in Hub. Datasets are encouraged to have complete, structured metadata.
Enable file geodatabase downloads
File geodatabase downloads can be automatically generated for hosted feature services that have allowed data exports. Each hosted feature service will need to individually be set to allow data exports. To learn how to allow data exports, refer to the ArcGIS Online help on managing hosted web layers.
After you have enabled data exports on your hosted feature service, you will need to reindex the dataset before the file geodatabase option appears on the dataset on your site. Once you have done this, the dataset will be available for users to download as a file geodatabase. If there is an error exporting the file geodatabase you will be notified in the Data Manager.
To remove the file geodatabase download option, turn off data exports for the item and reindex the dataset.
