Show definitions of standard types

Collections. A Collection is a systematic gathering of a specified selection of data or information for a particular stated purpose from existing records held within health and care systems and electronic devices.

Extractions. An extraction is a type of collection that is pulled from an operational system by the data controller and transmitted to the receiver without additional processing or transcription by the sender.

Information standards. Information standards are agreed ways of doing something, written down as a set of precise criteria so they can be used as rules, guidelines, or definitions.

Technical Standards and specifications. Technical standards and specifications specify how to make information available technically including how the data is structured and transported.

It starts with the customer, who can place orders, receive invoices, and has one or more delivery addresses. Each delivery address can be linked to several orders. Every order includes order items, and each order item is linked to a product. Products belong to a product category, which helps group similar items together. An invoice is linked to the order it covers, and customers are responsible for their invoices. The diagram helps explain how customers, products, orders, and delivery information all work together in a shopping system.

At the top is a general group called Animal, which includes all animals in the diagram. Every animal has an age (a number), a gender (a word), and two actions they can do: isMammal, which checks if the animal is a mammal, and mate, which means to have babies. There are three types of animals shown: Duck, Fish, and Zebra. Each one belongs to the Animal group but also has its own special features. Ducks have a beak colour and can swim and quack. Fish have a size in feet (which is private) and can eat. Zebras have a wild or not setting and can run. This diagram helps explain how animals can be sorted into a general group with shared traits, while still keeping their unique features.

Both scores range from 0 to 1, where 1 is the highest possible score, meaning the campaign reached or engaged with everyone in the target group. The chart is split into four areas to make it easier to understand. Campaign C (0.57 reach, 0.69 engagement) and Campaign F (0.35, 0.78) are in the top right, showing high reach and high engagement — these fall under “We should expand.” Campaign A (0.3, 0.6) has strong engagement but lower reach, so it’s in the “Need to promote” area. Campaign D (0.78, 0.34) has good reach but low engagement and may need improving. Campaigns B (0.45, 0.23) and E (0.40, 0.34) have lower scores for both and may need to be re-evaluated. title Reach and engagement of campaigns x-axis Low Reach --> High Reach y-axis Low Engagement --> High Engagement quadrant-1 We should expand quadrant-2 Need to promote quadrant-3 Re-evaluate quadrant-4 May be improved Campaign A: [0.3, 0.6] Campaign B: [0.45, 0.23] Campaign C: [0.57, 0.69] Campaign D: [0.78, 0.34] Campaign E: [0.40, 0.34] Campaign F: [0.35, 0.78]

The chart shows that on Monday, 60 minutes were spent training, Wednesday had 120 minutes, Thursday had 180 minutes, Friday had 230 minutes, and Saturday had the most time trained with 300 minutes.

The next milestone is "Prototype standard:", which is tagged with version v1.0.0, indicating the first official version of the prototype. After that, the project reaches the "FCAP approved" stage, followed by the "Review" phase, which is tagged with RC_1, representing the review for release candidate 1. The project then moves to the "Standard published" milestone, marking the official publication of the standard. Following that, the "Adopted" stage is highlighted and tagged with version 8.8.4, showing that the standard has been formally accepted. Finally, the project reaches the "Retired" stage, signifying the end of its active development phase. commit id: "Front door" commit id: "Prototype standard:" type: NORMAL tag: "v1.0.0" commit id: "FCAP approved" commit id: "Review" type: REVERSE tag: "RC_1" commit id: "Standard published" commit id: "Adopted" type: HIGHLIGHT tag: "8.8.4" commit id: "Retired"
