Items are the contents available in an ArcGIS Enterprise organization. Each item includes an item page with a variety of information, options, and settings. Browse or search the organization for items, click the item title to get a preview of what each item contains and how to use it, and open the item page to access more information about the item.
Tip:
The information and options available to you depend on the item type, your privileges, and whether you are the item owner or an organization administrator. Only item owners or organization administrators can configure an item's settings.
Item pages allow you to explore items in depth in a variety of ways. For example, an interactive attribute table integrates related records and attachments, allowing you to explore attribute data and view all aspects of a field together, including field values, summary statistics, and settings. Content creators and administrators can change an item's settings without having to go to other places on the site. For example, you can configure an app from a scene on the Overview tab or edit app settings directly on the Settings tab. Feature layer styles, pop-ups, and other layer properties can be configured on the Visualization tab as an alternative to opening the layer in a map viewer.
Open the item page
To access an item page, do one of the following:
- From the gallery, click the Options button
and click View details.Tip:
Click the thumbnail of an item to open the item preview, which provides a quick view of an item's details. If the item contains what you need, click View details on the item preview pane to open the full item page.
- From any tab in the Content page, click the item title.
Tip:
Click Preview to open the item preview, which provides a quick view of an item's details. If the item contains what you need, click View details on the item preview pane to open the full item page.
- Click the item name when searching for layers in a map viewer.
Sublayers in feature and table layers
Individual sublayers in a feature layer or table layer have their own pages that contain information and functionality that pertain to and affect the sublayer only. To access details for a sublayer, open the item page for the feature or table layer and click the sublayer in the Layers or Tables list on the Overview tab.
You can do the following from a sublayer's page:
- Read a summary that is specific to the sublayer.
- Read a description that is specific to the sublayer.
- Discover attribution information for the layer. It is not uncommon for each layer to have a different source or origin.
- Copy the URL for the sublayer so you can reference the individual sublayer in another app.
- Open the sublayer in Map Viewer or Map Viewer Classic.
- Access each sublayer's metadata.
- View each sublayer's attribute data.
- Visualize the sublayer.
- If the item is a hosted feature layer and the layer owner or an organization administrator enables exporting, you can export the sublayer's data to another format.
- If you are the hosted feature layer owner or an organization administrator, you can enable or disable attachments for a sublayer.
To return to the details for the feature or table layer, click the layer name in the banner at the top of the sublayer page.
View overview information
The Overview tab includes a summary of information about an item that explains what the item contains. Use the overview information described below to better understand the item before you use it.
Title
The title is the item name that is shown when you access the item. The title reflects what the item contains.
Summary
The summary is a short description of the item.
Item status
Organization administrators can indicate what items are the authoritative version of a particular set of data, a map, a scene, or an app. When an item is designated authoritative, an authoritative badge is shown near the top of the item's Overview tab.
For example, if the organization contains several layers representing roads, an administrator can identify the layer that is the most complete and accurate, and designate it as the authoritative layer.
When an item is outdated or is no longer needed, an administrator or the item owner can designate the item as deprecated. If that is the case, the deprecation label displays near the top of the item's Overview tab. The deprecation badge acts as a warning that the item may soon be deleted. It indicates that you should not use this item and, if you are using it, provides you time to find a replacement.
Tip:
Authoritative and deprecated badges also appear on the item on the Content page or search results. You can also use the status filter on the Content page to identify authoritative and deprecated items.
Developer information
Apps that are registered with the OAuth 2.0 credential, token, and redirect information appear with an OAuth 2.0 Application badge. This badge indicates to developers that they can use the information in the app item to allow users of the app to authenticate using their ArcGIS Enterprise credentials.
Description
The description provides in-depth information about the item.
Thumbnail image
The thumbnail image provides a visual representation of the item.
For layers, maps, and scenes, this is usually a preview of the item's content. However, the item owner or organization administrators can change the thumbnail image. For example, items related to the same project might include a thumbnail image that represents that project. For file-based items, the owner could add a thumbnail image that indicates the type of file it is or the type of information the file contains.
The thumbnail appears on the item page as well as the Content page when you view items in a list or grid.
Terms of Use
This section provides information about how the item can be used and by whom. For example, if you must display copyright information or credits to the source agency for a web map you use in a report or article, that information will be stated in the item's Terms of Use field.
Metadata
Metadata provides even more in-depth information about an item. If the item has metadata defined, you can click the Metadata button to view the item's metadata in the metadata style configured for the organization.
Individual layers in a multilayer feature layer can store metadata that is different than what is set for the feature layer. To access the metadata for a sublayer, click the sublayer in the Layers section on the feature layer's Overview tab.
Item ID
Every item in your organization is assigned a unique identifier (ID). This ID is part of the item's URL and is also available in the Details section of the Overview tab on the item page.
Developers who need to reference an item in their custom apps use the ID to ensure they access the correct item. They can copy the ID from the Details section to paste into code.
For examples of using an item's ID, see the following developer pages:
Image properties
If the item is a hosted imagery layer, the details and image properties are listed on the item page. Details include the size and image count of the imagery layer. Image properties include the source type, pixel type, number of bands, and cell size.
Level of sharing
Items are labeled to indicate who has access to them—the public, all organization members, members of specific groups, or only the item owner.
Before you use an item or share the item on social media, ensure that the item is configured for the appropriate level of sharing. For example, you cannot share an item to Twitter if the item is not shared with the public. Similarly, if you add a layer to a map and share the map with your organization, but the layer is only shared with one group, the layer will not load in the map for organization members who are not a member of that group.
The level at which the item is shared is visible under Share on the item's Overview tab, and also on the item in the Content page.
Credits (Attribution)
Attributions for the individual or agency who provided the data let you know where the data originated.
Attributions for layer items appear at the bottom of the map when you add the layer item to Map Viewer.
When attributions are set on the sublayers in a multilayer feature layer, the sublayer attributions appear in Map Viewer when you add the layer to a map.
Tags
Tags are added to items by the item owner or organization administrator to help people find the items when they initiate a search. In most cases, you won't read the tags on the item detail page unless you need to comment on the keyword tags that you expected for the item, and thereby help the item owner improve search results for the item.
Feature and table layer details
Feature layers and table layers include a Data tab in their item pages. You can view the attribute table for the layer on the Data tab using either of the following options:
- Table—When you view the attribute table using this option, all the fields (columns) and rows in the table, the fields and rows in related tables, and all the attribute data are shown. This view of the table is best when you want to view, sort, or edit or delete the attribute data stored in the table and when you want to view and add attachments, such as related photos or other files. Layer owners, organization administrators, data curators, and members of shared update groups can edit or delete attribute data.
You can also learn more about the individual fields—for example, determine whether a field is required or view its default value—by clicking the column header of the field and clicking Show Detailed View. The table is reduced in size to a more focused view of the field you selected, with a Summary section; a Settings section with field attribute rules, such as required fields and default value; and a Details section with information such as the field name and type. The information available in each section depends on the field type and your privileges. For example, in the Summary section, a histogram is shown for numeric fields, or a list of the top 10 unique values and associated count information are shown for text fields.
To choose a different field to explore without returning to the full table, click the Options button
and select a different field. After you finish viewing detailed information about a field, you can return to the full table view by clicking the Close button. - Fields—When you view the table from the Fields page, a list of all the fields in the attribute table is shown, including hidden fields and fields from related tables. You can filter for specific data types and change the list order of the fields on the Fields page by clicking the Sort by button. For more information about a particular field, click the field's Display Name setting.
If the layer owner or administrator defined a description or type for each field, this information displays on the Data tab. This helps you determine how to represent the fields in your maps and what information is required when you edit attributes in the layer.
Note:
For feature layers that contain multiple layers, you can work with the attributes and fields of the individual layers by first selecting the layer from the Layer drop-down menu. If you click the Data tab on the page of an individual sublayer, the Layer drop-down menu is not available. All changes you make on a sublayer's Data tab apply only to that sublayer, and you cannot switch between sublayers.
View attributes
Attribute data for a feature layer item can be viewed in the attribute table. Do either of the following to view attributes:
- To make it easier to view attribute data, sort the attributes by clicking the column header and selecting Sort Ascending or Sort Descending.
Note:
Some older versions of ArcGIS Server may not support sorting.
- To hide or show attribute fields, click the Show/Hide Column button at the top of the table. Check the boxes to show attribute columns. Uncheck the boxes to hide them.
Tip:
If the layer is an editable hosted feature layer, data curators and members of shared access groups can edit or delete attributes. To edit an attribute in the table, select the value in the cell, type a new value (or remove the value if you want to delete it), and press Enter to save your changes.
View related records, photos, and files
If a layer has related records, those appear in the Table view of the Data tab. These related records are represented as columns with italicized headers on the side of the table.
You can view related photos or other files for an attribute if attachments are enabled on the layer.
Do any of the following to view related records, photos, or files:
- To view related records, click Show in the cell in the related table column corresponding to the record with the related records you want to view. For example, if a parcels layer has a related table of owners and you want to view all the owners of a parcel, click Show in the appropriate cell of the Owners column to view a list of owners for the selected parcel. From there, you can explore other records in the table—for example, select another parcel ID to view the owners of that parcel. If the related table has related records of its own, you can examine those as well—for example, if the Owners table has a related table of other properties owned by a parcel owner, click Show to view those property records.
- When viewing a related table, click the Close button at any time to return to the previous table.
- If the layer has related photos or files, view them by clicking Show in the appropriate cell of the Photos and Files column on the table. To add an attachment, click Add and upload the photo or file.
- To hide or show related tables or photos and files columns, click the Show/Hide Column button at the top of the table. Check the boxes to show the columns. Uncheck the boxes to hide them.
Tip:
If the layer is an editable hosted feature layer, related records can also be edited. To edit an attribute in a related table, select the value in the cell, type a new value (or remove the value if you want to delete it), and press Enter to save your changes. Only those with privileges to edit features can edit attributes in related tables.
If attachments are enabled on the layer and you have privileges to edit, you can add photos and files to features in the layer.
Options that allow you to interact with the item
If, after reading the item information, you determine the item meets your needs, you can use options on the Overview tab to do the following:
- Open or download the item. (Options to open the item are also present on the item preview pane.)
- Add the item to a list of your favorites. (The option to add the item to your list of favorites is also available on the item preview pane.)
- Add a rating or comment to the item.
- Copy the source URL for items that have them, such as web services or web apps.
- Share the item to social media sites.
Some types of item pages have additional options. For example, you can explore and change how you visualize feature layers, publish apps from the item page of configurable apps, create an app from a web map or web scene, and export data from export-enabled hosted feature layers.
Open or download items
The action buttons available on the Overview tab of the item page or the preview panel depend on the item type.
By default, items open in the most appropriate app. For example, maps open in Map Viewer or Map Viewer Classic, scenes open in Scene Viewer, and layer packages open in ArcGIS Pro. Sometimes other options are available. For example, you may be able to open a map in ArcGIS Pro instead of Map Viewer.
You can open the sublayers of a feature layer in Map Viewer or Map Viewer Classic only.
Some items, such as files, can be downloaded. Once you save the file to your local machine, you can open it in the appropriate software.
Maintain a list of favorite items
You can create a list of favorite items to make it easy to access items you use frequently.
To mark an item as a favorite, click Add to favorites below the thumbnail of the item on the Overview tab.
You can view the list of items from the My favorites tab on the content page and when you search for layers to add to a map.
To remove a favorite item from the list, click Remove from favorites below the thumbnail of the item on the Overview tab.
Add ratings and comments
Ratings and comments can help content creators and other users assess the usefulness of an item.
Each item page includes a rating. Ratings are based on a weighted average of five stars, with one star indicating a poor item and five stars indicating a great item. The rating value provides a weighted average that factors in the number of ratings an item has received as well as the average rating. For example, an item with two ratings of four stars each has a higher rating than an item with one rating of four stars. To rate an item, you must be signed in and can only rate items you don't own. You can only add one rating per item. While you can change your rating, the count remains the same. To rate an item, click the appropriate star in the Details area on the side of the Overview tab.
Item pages can also include a section for comments, depending on whether your organization administrator enables them. Comments appear at the bottom of the Overview tab and can be added by the item owner or other signed-in users. Once you publish a comment, you can delete it, but you can’t edit it. People who are signed in can also reply to a comment. Item owners can delete comments published for items they own. Use the Sort by option to sort comments from newest to oldest (New) or by most recent reply (Latest Reply). You can subscribe to an RSS feed of comments for an item that is shared with everyone (public). You cannot subscribe to comments for an item that is only shared with your portal (or that is private).
Copy the URL
You can copy and paste the URL of an app, ArcGIS Server layer, or hosted layer and use it elsewhere. For example, developers can include the URL of a hosted web layer in apps they build.
For most items, you can also use the URL to access the REST endpoint for the service that populates the item.
Share an item page through Facebook or Twitter
Each item page may include a Facebook button 
and a Twitter button 
you can use to quickly share content through your
Facebook and Twitter accounts. (If these buttons are not available, your organization administrator may not have enabled them, or you may not have privileges to share with the public.) You can share the item page of any item
in the portal including those owned by others. It's a good idea to
share only pages for items that you know are shared
publicly; otherwise, some people may not be
able to access the links.
When you use the Facebook and Twitter buttons on an item page, you are sharing the item details, not the item. To share a map (as opposed to its item page), use Share on the map.
Explore feature layers
The item page of a feature layer includes a Visualization tab. On the Visualization tab, you can make changes to the default properties of a feature layer without opening the layer in a map viewer. You can change the layer’s style, apply a filter, configure pop-ups, or label the features in the layer. You can also hide the layer in the legend or change the refresh interval. As in Map Viewer or Map Viewer Classic, the Visualization tab provides tools to explore the layer and access the basemap gallery, as well as a search box to find an address or place.
Note:
The Visualization tab supports both map viewers. If a feature layer has been configured and saved in Map Viewer, the layer appears on the Visualization tab using Map Viewer. Otherwise, the Visualization tab uses your organization's primary map viewer or the primary map viewer set on your profile.
If you own the item, you can save changes you make to the layer. Both the item owner and those who have privileges to create content can also save a copy of the layer as a new item in My content.
Some of the properties you can configure on the Visualization tab are listed below.
Note:
If the feature layer contains multiple layers, use the Layer drop-down menu to select a sublayer. If you click the Visualization tab on the sublayer's page, the Layer drop-down menu is not available; all the changes you make are automatically applied to the sublayer.
- Change the style: Map Viewer, Map Viewer Classic
- Apply filters: Map Viewer, Map Viewer Classic
- Configure pop-ups: Map Viewer, Map Viewer Classic
- Configure labels: Map Viewer, Map Viewer Classic
- Set layer refresh interval: Map Viewer, Map Viewer Classic
- Search locations and features: Map Viewer, Map Viewer Classic
- Navigate the map: Map Viewer, Map Viewer Classic
- Choose a basemap: Map Viewer, Map Viewer Classic
- Save changes to a layer: Map Viewer, Map Viewer Classic. This option is available for item owners, administrators, or shared update group members.
