Introduction to faceted taxonomy
Faceted classification classifies objects using multiple taxonomies that express their different attributes or facets rather than classifying using a single taxonomy.

Sports Competition policy
• 307 of 1149 MediaTopics are sports terms. SubjectCodes has 585!
• Class of competition defined in each sport is highly inconsistent.
• What is the appropriate level of granularity?
5
Sports Competition policy
The competition disciplines section of Media Topics should contain terms for sports competed at a professional or elite level.
Sub-sport (discipline) terms may be added where different rules, techniques, and/or equipment significantly differentiate competitions.
In sports where all athletes typically train and compete in all events, individual event terms are not appropriate.
Additional description of competitions or events should be defined using facets.
6
What are these facets?
• Distance
• Time
• Number of athletes competing in a team
• Level of competition
• Weightclass
• Age
• Gender
• Ability level of participants
7
How will we express facets?
• Many are already in the Subject Qualifier vocabulary.– http://cv.iptc.org/newscodes/subjectqualifier/ – Covered: gender, indoor/outdoor, many competition
levels, stage– Partially covered: ability level, team size, age– Candidate: weightclass
• ODF covers ability level thoroughly.
8
How will we express facets?
• Scalar values – distance and time– SportsML has the syntax to express scalar values and
units.– No need for additional controlled terms.
• Ranges – age of athletes– Minimum and maximum ages– Conceptual ranges – junior, senior, etc.– Needs more discussion
9
How will we express facets?
• Team size– Subject Qualifiers defines individual, duet, and team.– Do we need controlled terms for some sports? Or
can team size be a scalar value?

Next steps
• Provide your expert feedback!• Join NewsCodes dev calls for discussion.
• Update Subject Qualifiers.• Continue discussion on age ranges, team size.• Re-consider decisions on swimming,
gymnastics, rowing• Create facets vocabulary.• Document best practice for combining facets
into individual terms
