Idea: Knowledge Views

# Idea: Knowledge Views

Something I'd appreciate as part of my knowledge bases is **saved views**: a declarative way to query, organize, and present a collection of knowledge objects.

Examples include Obsidian Bases and Notion database views.

They typically provide:

- selecting a source collection
- filtering objects
- sorting results
- grouping results
- defining derived fields
- choosing a presentation format

It may be useful for the Knowledge Catalog project to define a lightweight, implementation-neutral **Knowledge View** artifact.

The analogy is a SQL view:

- Knowledge objects remain the source of truth.
- Views are derived artifacts.
- Views describe how knowledge should be selected, organized, and presented.
- Multiple tools can interpret or render the same view definition.

For example, a knowledge object might contain:

```yaml
type: project
status: active
owner: matthias
priority: high
```

A corresponding view could express:

```yaml
source:
collection: projects

filter:
status: active

sort:
- priority: desc

group:
by: owner

presentation:
preferred: table
```

My primary use case is currently human-facing, but I assume AI agents could benefit from this as well, especially with some guidance and when paired with scripts or skills.

I understand the complexity of standardizing a query language, but I find these views highly practical, so I wanted to get the discussion going.

WDYT?
