In uSmart you can allow people from other organisation to add data via their shared user accounts (see here). And you can also enable them to add their organisation's logo and name to a dataset so it appears in data searches. This is done in the management section, under data providers, where you provide a logo and the organisation name.
Once the provider is added then you can select within a dataset from the dropdown menu of all Data Providers added for your organisation in the management pages.
The name then appears within the metadata for that dataset and as an additional logo. Illustrated below where Glasgow City Council provide cycling data to the Active Travel Open Data site provided by Cycling Scotland.
