## API
[Generated API docs](https://docs.thi.ng/umbrella/prefixes/)
This package only contains constants, no actual code. Please see [source
code for full list
provided](https://codeberg.org/thi.ng/umbrella/src/branch/develop/packages/prefixes/src/).
**Note:** some namespace URIs exist in two flavors - for RDF vocab and
as XML namespace. The latter versions are always prefixed with `XML_`,
e.g.:
```ts
import { xsd, XML_XSD } from "@thi.ng/prefixes";
xsd // http://www.w3.org/2001/XMLSchema#
XML_XSD // http://www.w3.org/2001/XMLSchema
```
### Usage with @thi.ng/hiccup
All current
[@thi.ng/hiccup](https://codeberg.org/thi.ng/umbrella/src/branch/develop/packages/hiccup)
consumers/processors support [RDFa](https://www.w3.org/TR/rdfa-core/)
attributes and specifically allow the `prefix` attrib value to be given
as object of prefixes. This allows for very compact prefix definitions
like so:
```ts
import { serialize } from "@thi.ng/hiccup";
import { article, body, div, h1, html } from "@thi.ng/hiccup-html";
import { dc, schema } from "@thi.ng/prefixes";
serialize(
html({ lang: "en" },
body({ prefix: { dc, schema } },
article({ resource: "/posts/hello-world", typeof: "schema:BlogPosting"},
h1({ property: "dc:title" }, "Hello World"),
div({ property: "schema:articleBody" }, "...")
)
)
)
);
```
Serialized HTML/RDFa result:
```html
Hello World
...
```
