8 Relating the Elements F Concerns –How are elements grouped? –What’s mandatory? What’s not? –What can repeat? How many times? F The standards use “production rules” with a special syntax to describe this information. F The graphic representation uses nested boxes, shading, and labels.

9 How Are Elements Grouped? F Compound elements are composed of other compound or data elements. The composition is represented by nested boxes. Compound Element 1 Compound Element 1.1 Data Element Data Element Data Element 1.2

10 Compound Element 1 Compound Element 1.1 Data Element Data Element Data Element 1.2 How Are Elements Grouped? Compound elements are composed of other compound or data elements. The composition is represented by nested boxes. Compound Element 1 is composed of Compound Element 1.1 and Data Element 1.2

11 Compound Element 1 Compound Element 1.1 Data Element Data Element Data Element 1.2 How Are Elements Grouped? Compound elements are composed of other compound or data elements. The composition is represented by nested boxes. Compound Element 1.1 is composed of Data Element and Data Element

12 Compound Element 1 Compound Element 1.1 Data Element Data Element Data Element 1.2 How Are Elements Grouped? Compound elements are composed of other compound or data elements. The composition is represented by nested boxes. Compound Element 1 is composed of Compound Element 1.1 and Data Element 1.2 Compound Element 1.1 is composed of Data Element and Data Element

13 What’s Mandatory? What’s Not?

14 What’s Mandatory? What’s Not? Mandatory - must be provided. Meaning Data Element Compound Element

15 What’s Mandatory? What’s Not? Mandatory - must be provided. Meaning Data Element Compound Element Mandatory if Applicable - must be provided if the data set exhibits the defined characteristic.

16 What’s Mandatory? What’s Not? Mandatory if Applicable - must be provided if the data set exhibits the defined characteristic. Optional - provided at the discretion of the data set producer. Mandatory - must be provided. Meaning Data Element Compound Element

17 What’s Mandatory? What’s Not? Mandatory if Applicable - must be provided if the data set exhibits the defined characteristic. Optional - provided at the discretion of the data set producer. Mandatory - must be provided. Meaning Data Element Compound Element Color and Shaded Versions

18 Compound Element 1 (can be repeated unlimited times) Compound Element 1.1 Data Element Data Element Data Element 1.2 If an element can be repeated independently from other elements, a label below the element name states how many times the element may be repeated. If there is no label, the element does not repeat independently from other elements. In the illustration, Compound Element 1 can be repeated an unlimited number of times. Thus, the following block of data is repeated: Compound Element 1 Compound Element 1.1 Data Element Data Element Data Element 1.2 What Can Repeat? How Many Times?

19 Making Decisions About Documenting Your Data Decision 1 Decision 1.1 Decision Decision Decision 1.2

20 Decision 1 Decision 1.1 Decision Decision Decision 1.2 Making Decisions About Documenting Your Data F Work down the columns.

21 Decision 1 Decision 1.1 Decision Decision Decision 1.2 Making Decisions About Documenting Your Data Decisions about higher-level elements (outer boxes) influence decisions about lower-level elements (inner boxes). So, for example, decision 1 usually influences decision 1.1 and 1.2.

22 Decision 1 Decision 1.1 Decision Decision Decision 1.2 Making Decisions About Documenting Your Data Decisions about elements at the same level usually are made independently. So, for example, decision 1.1 and decision 1.2 usually are made independently of each other.

23 Decision 1 Decision 1.1 Decision Decision Decision 1.2 Making Decisions About Documenting Your Data Work down the columns. Decisions about higher-level elements (outer boxes) influence decisions about lower-level elements (inner boxes). So, for example, decision 1 usually influences decisions 1.1 and 1.2. Decisions about elements at the same level usually are made independently. So, for example, decision 1.1 and decision 1.2 usually are made independently of each other.

24 Using the Graphics to Make Decisions - 1 All elements are colored yellow, so all are mandatory and must be reported. MM / AO Compound Element 1 Compound Element 1.1 Data Element Data Element Data Element 1.2

25 Using the Graphics to Make Decisions - 1 All elements have no shading, so all are mandatory and must be reported. MM / AO Compound Element 1 Compound Element 1.1 Data Element Data Element Data Element 1.2

26 Using the Graphics to Make Decisions - 2 Compound Element 1 is mandatory. Compound Element 1.1 is optional. The producer must decide if it wants to provide the element. If yes, Data Elements and are mandatory. If no, do not report Compound Element 1.1, Data Element or 1.1.2, and skip to Data Element 1.2. Data Element 1.2 is mandatory. MM / AO Compound Element 1 Compound Element 1.1 Data Element Data Element Data Element 1.2

27 Using the Graphics to Make Decisions - 2 Compound Element 1 is mandatory. Compound Element 1.1 is optional. The producer must decide if it wants to provide the element. If yes, Data Elements and are mandatory. If no, do not report Compound Element 1.1, Data Element or 1.1.2, and skip to Data Element 1.2. Data Element 1.2 is mandatory.

28 Using the Graphics to Make Decisions - 3 Compound Element 1 is mandatory. Compound Element 1.1 is mandatory. Data Element is mandatory. Data Element is mandatory if applicable. The producer must decide if the data set has the characteristic defined by the data element. If yes, then Data Element is mandatory. If no, then Data Element is not reported. Data Element 1.2 is optional. MM / AO Compound Element 1 Compound Element 1.1 Data Element Data Element Data Element 1.2

29 Using the Graphics to Make Decisions - 3 Compound Element 1 is mandatory. Compound Element 1.1 is mandatory. Data Element is mandatory. Data Element is mandatory if applicable. The producer must decide if the data set has the characteristic defined by the data element. If yes, then Data Element is mandatory. If no, then Data Element is not reported. Data Element 1.2 is optional. MM / AO Compound Element 1 Compound Element 1.1 Data Element Data Element Data Element 1.2
