Metadata in SharePoint Online is used to find and manage files. The metadata may be free-form text or numbers entered by users, or it may have pre-defined values and vocabularies that users pick or are set as default on the storage container, e.g., company name, department, country, process, document type. The latter makes it easier to find information in and across SharePoint sites. It can also be used to as search results refiners like in the example below. This does requires mapping in the search administration. Advanced search allow users to search using metadata.
Metadata is often just a list of values, e.g., companies, processes, document types. If the list is long, it often makes sense to group it into a a tree or hierarchy, e.g, processes with sub-processes, document types with sub-document types. Most metadata should be set as default on the storage container when the site is set up, e.g., using the free Infotechtion Teams Hub. If users have to manually enter any metadata, then change management is key. Users will then have to see the value and importance of adding the metadata, and you need ongoing monitoring and governance to identify and address those users that don´t do it.
If users have to manually add some metadata, they can do this by writing what they think is the correct term and SharePoint auto-suggests the available tags.
Users can also press the tag symbol to see all available metadata values.
If the list of values is long, e.g., countries in the world, then this should be grouped to make it easier for users to find the correct value, e.g. countries per continent.
The challenge is metadata hierarchies that should enable users to tag, filter and find files at any level in the metadata hierarchy. Let me share a simple example of this and your options.
You have some documents covering continents, and others covering countries within the continent.
Document 1 about Europe
Document 2 about the Netherlands
Critical success factor: If I search for Europe, I should find documents both Europe and countries within Europe like the Netherlands
You can achieve this by two different approaches. The best approach depends on use case. For continents and countries, we often end up with option 1. For document type and sub-types, we often end up with option 2.
Option 1: Two metadata values / columns
Column A: Continent
Column B: Countries grouped by Continent
Impact:
The deeper the hierarchy, the more repetition for users since they will have to pick the top-values many times to select lower values (e.g., Europe and then Netherlands)
No relationships between the columns when filtering search results since columns are not connected
More metadata on the document: Europe and the Netherlands
Option 2: One metadata value / column
Column C: Hierarchical values with Continent as parent and Countries as children
Impact:
Reduces the number of clicks to tag documents
Customization required to show hierarchy as search result filters
The relationships is managed in M365 which means you will find files about the Netherlands when searching for Europe, but the file only get the last tag as metadata: the Netherlands
