Below are a few of the commonly asked questions we receive about Data Lens:
Why am I not able to create a Data Lens page?
There are a few factors required to create a Data Lens. First, you need to have Publisher or Administrator permissions in order to create the page. If you have the appropriate level of permissions, the Data Lens “Show Me” exploration image will display on the data set.
A Data Lens page can be created on a private or public published dataset. However, in order to make the Data Lens public, the underlying dataset has to be public.
For newly created datasets, there is a time delay of about an hour and a bit longer for larger datasets (>10mil rows) for the Data Lens “Show Me” button to display.
Data Lens pages cannot be built off of filtered views, only the source tabular dataset.
How up-to-date is the data on the Data Lens page versus the underlying dataset?
Updates to the underlying data and schema updates and changes (such as adding new columns or changing column names and descriptions) should be reflected in about an hour slightly longer if a large dataset.
How many Data Lens pages can be created per dataset?
Previously you could only create one Data Lens per dataset. There is no longer a limit to the amount of Data Lens pages that can be created from a dataset.
How do I delete a Data Lens page?
There is currently no way to delete a Data Lens page but you can control the permissions of who has access to the page. If “Public”, it will be available to all types of users and discoverable in the catalog. Site administrators are asked to reach out to Support at firstname.lastname@example.org if they would like a data lens completely removed from a domain.
Can a Data Lens page be federated to another Socrata domain?
Data Lens pages can be federated to another Socrata domain.
How are Data Lens pages counted in Site Analytics?
Visits to Data Lens pages will count in the total of page views for the site. There is a new type of chart that breaks down the different page views by page types. Data Lens is included as a particular data type. By selecting "Page Types" in the drop-down, you will see the traffic to the different page types over the selected time period.
Are Data Lens pages eligible to go through the routing and approval queue?
Yes! They will follow the process similar to any other view type.
How do I update the metadata associated with a Data Lens?
In order to update the metadata, add "/edit_metadata" to the end of the URL.
