Maintenance COD AB
Overview
Maintenance is an important step in the COD cycle as it ensures that the dataset is still relevant and accurate for humanitarian use. It is required once a year. The IM network should be asked if there are changes or new datasets they are aware of. If there are no changes, the IM Network should endorse the COD-AB already in use so all are aware of the COD that is officially in use. It is important to remember the link between COD-AB and COD-PS as a change in one may require changes in the other. If changes are required or a new dataset is identified then the COD cycle starts again.
Versioning occurs if there are changes to the dataset. It is a data management process that informs that a change has been made to the COD-AB. Versioning requires changes in the old dataset and its metadata (by providing language to indicate a new version of the dataset it available and timeline of the dataset). A new version of the dataset and metadata should be created when changes are made so clients can still access the former version of the COD.
Table 0: Initial Steps to identify if there is a new dataset available
Step | Step Details | Tips |
Find out if there is a new dataset available | Organize an IM network meeting to check if anyone has identified changes that need to be made or a new dataset that is available or better than what is currently in use OR if you have found a new dataset or changes required. |
|
Next steps in tables below | If there are changes or a new dataset see Table 1 below. Otherwise see Table 3 below. |
Table 1: Steps if there are changes to the COD or a new dataset is identified (yearly or ad-hoc)
Step | Step Details | Tips |
1. Organize an IM network meeting | Communicate to partners that a new COD-AB is available and get feedback if a change is required |
|
2. Start the COD cycle | Start the COD cycle: Plan, Collect, Process, Endorse. to get make the changes or process the dataset |
|
3. Version the data | Modify the old data set to indicate its time span |
|
4. Communicate that a new version of the COD is available | Share the new COD and metadata and archive the former COD's metadata on HDX |
|
5. Archive COD in your office | Place the old COD (all formats) in the archive folder and follow archiving steps |
|
5. HDX communicates to FIS | HDX notifies FIS of updates |
|
6. FIS endorses COD | FIS uses the Yearly Quality Check to verify the data and endorse. |
|
Table 2: HDX metadata changes when there is a new version
HDX metadata element | Former (old) COD (example) | Current (new) COD (example) |
Tag | Remove COD tag | Add COD tag |
Title | Include (validate from and to dates) | Include year it was endorsed |
Description | •Say it is an “old” or “former” COD •Include the “retirement date: YYYY/MM” | •Include “COD was endorsed by IMWG YYYY/MM” |
Caveats | •Link to new COD | •Link to old COD it is replacing •Details about the update |
Table 3: Steps in there are NO known changes to the COD (yearly)
Step | Step Details | Tips |
1. Organize an IM | Discuss continued endorsement of the same COD-AB for the next year or until a new dataset is found or changes identified. | |
2. Communicate that the COD has been endorsed again | Update metadata on HDX to reflect the new endorsement date |
|
Table 4: Steps To Archive In Your Office
1. In the \\COD\AdminBdy\COD_XXX folder create a new folder called ‘Archive’ |
2. Within the ‘Archive’ folder, create a new folder called “Archive_XXX_validTo_[Date]” Replace the [Date] with the actual validTo date, which will be the same as the validOn date for the new candidate |
3. Move the ENTIRE contents of the AdminBdy\COD_XXX folder to the “Archive_XXX_validTo_[Date]” folder |
4 .Edit the old candidate datasets to populate the validTo date fields for the features and the metadata |
6. Rename the XXX_Evaluation_Checklist to Archive_XXX_Evaluation_validTo_[Date]” - as above replace the [Date] with the actual validTo date, which will be the same as the validOn date for the new candidate |
