Hypertext Application Language (HAL) is an Internet Draft (a “work in progress”) standard convention for defining hypermedia such as links to external resources within JSON or XML code. The two associated MIME types are media type: application/hal+xml and media type: application/hal+json. HAL was created to be . Ion parsers MUST identify any JSON object as an Ion File either a type member equal to the octet sequence file or the. “Hypermedia Types are MIME media types that contain native hyper-linking semantics that induce application flow. For example, HTML is a hypermedia type; .

If data can be submitted to a linked resource location, information about that data must be made available to a hypermedia client so it can hipermeddia and then submit the data. The minlength member is a non-negative integer that specifies the minimum number of characters the field value must contain.

If the Root Object is also found to be an Ion Link, typfile has an implicit link relation type of self. Clicking on link might play a sound, another a video, or another would take you to a different card. However, by having these relationships already drawn out as suggestedthe additional time required will be minimal.

HAL – Hypertext Application Language

It presents some snapshots and links to other sections of websites. Instead, the representation of the linked resource is supposed to be embedded as an image in the current document. Another approach to communicate links with json responses, is using a Link response header: For example, a Collection Object could have an eform “element form” member to represent the structural ‘form’ of each element in the value array instead of repeating this information in fypefile array element:.

The max member value may only be defined when the type value is equal to numberintegerdecimaldatedatetimedatetimetztimeor timetz as defined in Ion Value Object Type Values. Hypermedia connects resources to each other, and describes their capabilities in machine-readable ways. This specification registers the Member Names defined in Section 7.

Names may not match other registered names in a case-insensitive manner unless the Designated Expert s state that there is a compelling reason to allow an exception in this particular case. The server is making a promise to the client: If an Ion Value Object has an array type and the Ion Value Object also contains minminlengthmaxmaxlength or pattern members, those members’ validation rules apply to each element in the value array, not the array itself.

The resulting object will be added to the Form Submission Object as a member having the same name as the field name.
