Hi,
I am doing some research for the CN AI WG and was processing the landscape.yml list. Not sure if this is ok, but found a few projects that are listed more than once. I can envision that happening, but given the the first one I checked (Apache Spark), it is unclear if its right.

% curl -s https://raw.githubusercontent.com/cncf/landscape/refs/heads/master/landscape.yml | yq -p yaml -o json | jq '.landscape[].subcategories[].items[].name'  | sort | uniq -c | sort -n
... (all above here are listed 1 time)
  1 "youki"
   1 "zot"
   2 "Alluxio"
   2 "Apache Spark"
   2 "Cassandra"
   2 "ClickHouse"
   2 "DeepFlow"
   2 "Grafana"
   2 "Kafka"
   2 "Numaflow"
   2 "Okahu"
   2 "OpenLIT"
   2 "OpenLLMetry"
   2 "Permify"
   2 "Presto"
   2 "Prometheus"
   2 "Pulsar"
   2 "Redis"
   2 "SpiceDB"
   2 "Upbound (member)"
   2 "Weaviate"

Just to on Apache Spark, it is listed as subcategories:

• Streaming & Messaging
• Data Architecture

I would not list Spark as streaming and messaging. Sure it streams things, but thats not the point of it. I think Data Architecture is fine.

Not to nit pick one entry, is there a rule about being listed more than once?
