# Skills Taxonomy Construct

- [Introduction to IYS Skills Taxonomy](https://docs.itsyourskills.com/skills-thoughts/skills-taxonomy-construct/introduction-to-iys-skills-taxonomy.md): IYS Skills Taxonomy is a database of "skills". Many of the facets of the Skills Taxonomy have been discussed in the previous section. Here we will go little bit more into the technical aspects.
- [Layer 1 - Unique Skills](https://docs.itsyourskills.com/skills-thoughts/skills-taxonomy-construct/layer-1-unique-skills.md): In this layer "skills" are aggregated, cleaned and normalized.
- [Layer 2 - Master](https://docs.itsyourskills.com/skills-thoughts/skills-taxonomy-construct/layer-2-master.md): "Skills" terms are grouped based on their relevance.
- [Layer 3 - Association](https://docs.itsyourskills.com/skills-thoughts/skills-taxonomy-construct/layer-3-association.md): Skills and skills groups are organized and assigned different properties. There are three types or organization and several properties that can be assigned to nodes.
- [Properties to Skills](https://docs.itsyourskills.com/skills-thoughts/skills-taxonomy-construct/properties-to-skills.md): Different properties can be assigned to skills. Properties impact the way the skills are rendered in the frontend, information collected from the users and others.
- [Process for Constructing Areas](https://docs.itsyourskills.com/skills-thoughts/skills-taxonomy-construct/process-for-constructing-areas.md): Areas of functions are bringing terms and  groups of terms in knowledge, expertise with tools & technologies, activities, domain experience and operational role as applicable for the area.
