# tag (0-tag.us)

A tag is a small label you stick on something to identify it or sort it. People tag photos with friends' names, or use price tags at stores. It is a quick way to mark what something is.

## What a model may hear
- HTML/XML element marker (web development and markup languages): treat it as angle-bracket syntax for structuring documents, or expect valid nesting rules
- version control label (Git and software development): assume a named reference to a specific commit, often for releases
- classification metadata (databases and content management): expect key-value pairs or taxonomy entries for filtering and search
- entity label in NLP (natural language processing and machine learning): interpret as part-of-speech or named-entity annotation for training data
- RFID or physical tracker (hardware and logistics): assume a radio-frequency identification device or sensor

## Where people and models part ways
- Says: "Tag me in that photo"
  Means: Put my name on the photo so I see it
  May be taken as: Generate HTML anchor tags or attempt to create metadata schema
  Say instead: "Add my name to the people shown in this photo"
- Says: "Tag the important ones"
  Means: Mark which items matter most
  May be taken as: Apply machine-learning labels or create a Git release tag
  Say instead: "Mark which items are highest priority"
- Says: "Can you tag along?"
  Means: Come with me
  May be taken as: Attempt to append a metadata label to a person or create a tracking entry
  Say instead: "Come with me"
- Says: "Remove the tag"
  Means: Take off the physical label
  May be taken as: Delete an HTML element, Git reference, or database index
  Say instead: "Take off the physical sticker or label"

## Tips
- Say 'label' instead of 'tag' when you mean a physical sticker
- Say 'HTML element' or 'markup' when you mean angle brackets in code
- Say 'label this data' rather than 'tag this data' to avoid machine-learning assumptions
- Specify 'name badge' or 'price sticker' for physical identification objects
- Use 'bookmark' or 'save' instead of 'tag' when you mean marking for later retrieval

## Often confused with
- label: more often means a physical sticker or printed identifier
- flag: signals a warning or requires attention, not just identification
- mark: broader, can mean any sign or grade without structured metadata
- token: a standalone unit of meaning, not attached to something else
- hash: a computed identifier, not a human-chosen descriptive label
- mention: specifically alerts a person, does not categorize content
