# Nomen class

Namespace: [Grasshopper2.UI](https://developer.rhino3d.com/api/gh2/namespace/grasshopper2.ui.md) · Assembly: [Grasshopper2](https://developer.rhino3d.com/api/gh2/assembly/grasshopper2.md)

```cs
[IoId("00000000-0e65-44e3-a44e-f81c20ec53b1")]
public sealed class Nomen : IStorable, IEquatable<Nomen>, IComparable<Nomen>
```

Collates a set of descriptive properties of some entity. The Latinate archaic term 'nomen' was picked for this type since we needed both a short and otherwise unused name. Hence, 'Name', 'Id', 'Description', 'Label' or 'Tag' were not acceptable. Nomens will convert automatically from strings, provided they are formatted thusly: '[Chapter.[Section.]]Name[//Info]'
