Viewing Span Annotation Metadata in Phoenix UI

·Mar 21, 2025 04:50 PM

Hey folks, I'm using the span annotation API and including a metadata with my annotation. Is it possible to see this metadata on phoenix UI?

Yes, it is possible to see metadata associated with span annotations in the Phoenix UI. When you add metadata to your annotations, it is included in the span's attributes and can be viewed in the UI. According to the Phoenix documentation, annotations can include metadata, and this metadata is propagated to the example metadata in datasets, making it visible during experimentation and analysis.Would you like more detail on how to ensure your metadata is correctly formatted and appears in the UI?

Hey José M. - will get that done! We're doing a full revamp of annotations so please let us know if you see anything missing and what fields are important to you. https://github.com/Arize-ai/phoenix/issues/5917 Should be a quick fix. https://github.com/Arize-ai/phoenix/issues/6877

Hey Jose, I pushed a fix to show the individual span annotation's metadata. I also quickly got a note from Hamel. I'm guessing my fix is not quite what you need and that you want some sort of KV attribution on the spans to run queries and to do analysis? In any case LMK I'd love to chat about your workflow and how we could unblock it. LMK if you'd ever like to chat!
