FAQ: 

1. What is a Data?

Data is a set of information which can be translated into a form for processing (http://searchdatamanagement.techtarget.com/definition/data)

2.What is a Metadata?

Metadata is data about data. Metadata describes how and when and by whom a particular set of data was collected. Metadata is essential for understanding the information stored and has become increasingly important in XML-based Web applications.

3. What is the purpose of Data Standards?

The adoption of Data Standards for use across e-Governance systems will enable easier, efficient exchange and processing of data. It will also remove ambiguities and inconsistencies in the use of data. The data standard enables the sharing or exchange of information between multiple users in a way that it guarantees same understanding of what is represented within that information. When exchanged information is comprised of structured data, a data standard provides the description of that structure. (http://www.knowledgeintegrity.com/columns/dmr200401.htm)

4. What is the meant by Metadata Standards?

Metadata standards are the requirements which are intended to establish a common understanding of the meaning or semantics of the data, to ensure correct and proper use and interpretation of the data by its owners and users. To achieve this common understanding, a number of characteristics, or attributes of the data need to be defined http://en.wikipedia.org/wiki/Metadata_standards

5. What is meant by Acronyms MDDS?

It means Metadata and Data Standards, where Metadata is structured minimal information that describes, explains, locates or otherwise makes it easier to retrieve, use or manage an information resource.

6. What is the purpose of Data Standards in e-Governance Applications?

The adoption of Data Standards for use across e-Governance systems will enable easier, efficient exchange and processing of data. It will also remove ambiguities and inconsistencies in the use of data.

7. What does the term “Generic Data Element” means?

The Generic data elements are usually defined as commonly used data elements, whose metadata needs to be standardised for interoperability in e-Governance applications within /across domains.

8. What does the term “Custom Data Element” means?

Custom data elements are derived from Generic data elements, specific to the requirements of an application within a domain. For example, Date is a generic data element, but Date of Birth; Date of Superannuation etc. are the custom data elements within an application. These custom data elements will follow the metadata defined for generic data element, Date. The custom data elements may have extended metadata (not standardised), to meet the specific requirements of the custom data element within the application.

9. What is the purpose of “Unique Reference Number” with reference to Standard?

The main purpose of “Unique Reference Number” is to link the identified Generic data elements with their respective metadata, and also to link it with custom data element derived from a particular generic data element.

10. What is the basis/authenticity of “Code Directories”?

The controlled values of generic data elements in the Code directories are given by the respective owners to the ORGI (Office of Registrar General of India), and is made available to different Domain applications through the Standard document- MDDS Demographic Ver 1.1, available on https://egovstandards.gov.in.

11. Why is the standard document “ Metadata and Data Standards for Person Identification and Land Region Codification Version 1.0” (MDDS Ver 1.0) titled as “MDDS- Demographic Ver 1.1”, in its revised version?

This change in the title has been done to keep it in line with
i) Nomenclature adopted for various domains specific Metadata and Data Standards like MDDS-PR (Panchayati Raj), MDDS-PDS (Public Distribution System) etc., which are in various stages of formulation.”
ii) The released document by UIDAI on, Demographic Data Standards and Verification Procedure, for establishing and verifying identity of a Person.

12. Why there is a need to use the 2011 Census code in place of 2001 Census codes of Land Regions?

The 2011 Census codes for Land Regions are Unique at National level and standardised. While upgrading the Codes to 2011 data, mapping with 2001 Census code is also provided for mapping new codes with codes in legacy applications. The mapping table is available on e-Gov Standards portal http://egovstandards.gov.in.

13. Why there is a discrepancy/duplicacy in village codes of 2001 and 2011 after the final list by ORGI?

The codes that have been referenced are not duplicate village codes. Actually, a lot of villages have been created in 2011 census due to splitting of villages, i.e., out of a single village, two or more than two villages have been formed. Initially, the Census Department had provided provisional codes to the new villages thus formed, by giving the census 2001 code of the village from which the village was created and suffixing that village code with 01,02,03 and so on to indicate that the specific village has been created by splitting an already existing village. However, when the Master location Codes were finalized, proper 2001 concordance was given against such villages/ towns so that proper figures could be obtained whenever required. That is why same 2001 Census location codes are shown against some villages/ towns.

14. Why in Town code directory, some of the sub-districts codes are given as “99999”?

In some States certain towns do not fall under any specific Sub-district. In such cases the Sub-district code for such towns has been given as "99999" to indicate that the towns are not in any Sub-district.

15. Why is there duplicacy of sub-district codes i.e. same sub-district name and code falling in different districts?

It is to submit that in certain states same districts and sub-districts are cutting across i.e, spread across 2 or more districts or sub-districts. In these cases the same name and codes have been given to the corresponding districts & sub-districts. Therefore, these districts and sub-districts are not duplicate but cutting across the boundaries. In the standard document a code directory CD02.06-01 is defined for the purpose of town cutting boundaries across Districts / Sub Districts.

16. What is the present Land Region Codification scheme of various domain specific applications?

The study of Codification followed by different Departments like, Election Commission, Land Records, Department of Post, Census and Rural Development, is being done on the basis of “Revenue Village”, for the purpose of Standardization at the National level.

17. What is meant by OGs?

OGs mean Out Growths, i.e. two or more physically contiguous towns together and any adjoining urban outgrowths of such towns. Examples of OGs are railway colonies, university campuses, port areas, etc., that may come up near a city or statutory town outside its statutory limits but within the revenue limits of a village or villages contiguous to the town or city. Each such individual area by itself may not satisfy the minimum population limit to qualify it to be treated as an independent urban unit but may deserve to be clubbed with the town as continuous urban spread.

18. Why there are some gaps while mapping the 2011 census codes with that of 2001, especially the case of Town (Lodhika) within State Gujarat?

Lodhika INA (INA) is a newly created town formed by combining parts of 3 existing villages. So, the 2001 one to one concordance has not been shown in this town as this is a case of one to many mapping. Only the codes upto Sub district level has been shown in 2001 mapping for this town.
