- More Whimsy UX to manage the Podling Lifecycle
- Consolidate podling status data
podlings.xml is still master
- Add status checklists and Incubation watchlist to the new Cookbook
- Whimsy podling status page will include clutch analysis
- We need to decide how to do reporting since MOIN wikis are going away. No recommendation is provided.
Podling Status Process
Here is an analysis of the many ways podling status is tracked by the Incubator. Currently there are five components to podling status.
- Podlings XML is directory listing ever podling and its status: current, graduated or retired.
- Podling Status Page is an XML/HTML file that has information about the podling's resource requirements and various checklists for the incubation process.
- Podling YML file which was started a few years ago as a data based approach to key resource and incubation process completions.
- The monthly / reporting process. This process a manual process involving the MOIN Wiki and a python program for creating the report template. This will need to be changed soon because the MOIN Wiki is being retired.
- Clutch analysis. This process takes the information from the Podlings XML and Status Pages and then looks for and confirms the Website, Issue Tracker, Wiki, Code Repositories, and Release Distributions.
What follows is a description of each of these processes. This will be followed by some ideas about how we should proceed.
The podling catalog is in this file:
Values are stored for all Incubator podlings in a single xml file each in a
podling node. Not all of the data pertain to current podlings.
- Podling name. This is set when the podling is created. It can be changed later but that can be expensive if the resources also need to be renamed.
- Status - This is one of these three values: “current”, “graduated” or “retired”. Podlings in the Incubator are current. When the podling exits it either “graduates” or “retires”
- Resource - This is the name used for resources. It is initialized to lower case of Podling name w/o spaces. Once the podling's resources are created it is very expensive to change these.
- ResourceAliases - If the podling's resource and name is changed the older resource names are stored in this field. Some older podlings had multiple names or short names for resources.
- Sponsor - Most often this is the “incubator”, but it may also be any Apache PMC if there are directly sponsoring a project in the incubator.
- Start date - This is the date that the podling starts incubation. It can be the date the podling entry is created or the date that the incubation vote passed.
- End date - This is the date the podling leaves the incubator. It is either the date that the Board votes to accept the graduation proposal, the date another PMC chooses to accept the podling as part of their PMC, or the date the podling retires.
- Description - a short description of the podling.
- Champion - the champion for the project.
- Mentors - a list of the podling's mentors with their Apache IDs. This is now maintained from Whimsy. Whimsy roster page
- Reporting group - which months is a current podling reporting to the IPMC. A new podling will be monthly.
- Resolution - when the podlings leaves the Incubator it either graduates or retires. These fields describe what happened,
- tlp attribute - If “true” the podling became a TLP
- link attribute - If a name change was involved to the new TLP, the podling graduates into an existing PMC, or retires with a new location then this is the text on a link.
- url attribute - If there is a link then this is the url.
- description - an optional description about retirement or graduation

Current format for Podling Status Files
More information is found on the project status page in xml wrapped html. For the most part this is descriptive text which has data embedded tagged with id attributes. There are also very descriptive check lists.
Here is the template for new podling status pages. You can see that it is a tedious process to copy this to add a new file for each podling.
This data is available and in some cases is extracted from these files by processes including the Clutch Analysis.
- Description - an HTML div which minimally repeats the podling description, but may include additional information about the podling's original location and resources.
- News - an HTML div with a list of dated events in the history of the podling.
- Project Info - an HTML table with a description and links to podling resources requested from infrastructure.
- www - Website url of the podling. It should be the website within Apache, but sometimes is the legacy.
- wiki - A url to the wiki. Sometimes this is blank if a Github wiki is being used. Not all podlings use wikis.
- mail-dev - The mailing list in various forms.
- mail-commits - The commits mailing list in various forms.
- mail-private - The private mailing list in various forms.
- tracker - a url to the issue tracker. Sometimes this is blank if Github issues are used.
- mentors - a set of rows which duplicate podlings.xml and are only hand maintained. Lately this is often shortened to point to the Whimsy roster page
- committers - a set of rows which are hand maintained. Lately this is often shortened to point to the Whimsy roster page
- Status reports. A list of board reports often pointing to the while incubator report. This is also now easily available from the Whimsy roster page
- Work Items
- Project setup. (very outdated instructions)
- Infrastructure. (outdated instructions)
- Mentor setup. (outdated instructions)
- Distribution Rights.
- Initial Committers. (outdated instructions)
- Incubation Items - what to watch for during incubation.
- Collaborative Development
- Licensing Awareness
- Project Specific
- Graduating into a TLP?
- Graduating into an existing PMC?
The status pages are sporadically maintained by a majority of podlings after bootstrap.
The Podling YML file
podling yml file the following parameters have values:
- asfCopyright - the date that the ASF copyright has been added to the donated code.
- distributionRights - the date that the code has been properly reviewed for appropriate licensing.
- graduationDate - the date of graduation.
- ipClearance - the date that the code has been properly reviewed for appropriate licensing.
- issueTracker - is github or jira used for issue tracking?
- jira - if jira is used provide the URL. The url can be assumed if the jira project key is the
podling.resource upper cased.
- news - a new place to put podling news records.
- proposal - the url to the podling proposal.
- sga - the date the software grant was received by the Secretary.
- sourceControl - only used once for ‘github’. Every project is using github.
- website - the project website url. This is always the preferred pattern.
- wiki - the Space key for a Confluence wiki.
You can see that there is quite a bit of overlap with information from the podling status page. This is intentional since the yml files are a replacement data store.
The key values are
Podling Report Template
The initial report template is created by
clutch2report.py. Look for the
perproject variable. The values
$description are taken indirectly from
podlings.xml via the
clutch2.pkl created by
clutch2.py. There is much more information available that can be injected into the template.
The podling maturity section has checkboxes which parallel some of the work items and checklists on the podling status page.
[ ] Initial setup
[ ] Working towards first release
[ ] Community building
[ ] Nearing graduation
[ ] Other:
Clutch analysis is performed using the
clutch2.sh shell script. The key programs in the process are the
clutch2.py python script which performs analysis pulling information from the following resources:
- Podling status pages
- Apache mailbox archive
- Gitbox Catalog
- Whimsy Project LDAP
- Whimsy Podling Website Scan
The results of the clutch analysis are published daily and appear on the Clutch Report. The shell script also runs
clutch2status.py which produces clutch analysis pages. The data is also written as a
This program was recently modernized and returned to relevancy.
An Improvement Plan
We have robust status information available for all the podlings, but have various gaps and incomplete transformations.
- The monthly report process must be adjusted. Two possibilities are available.
- Switch to use a process similar to what the Board uses for TLPs.
- Switch to Confluence process that looks like what we are doing now.
- The Podling YML file does a good job of handling the data that is on the Podling Status page. What is lacking is a clean UX to edit the data at the appropriate time.
- Editing the Podling.xml file by hand can become an issue when the DTD is not properly followed. Whimsy's podling roster page solves this for Mentors by handling that on its own.
- The Podling Status page mixes data with valuable recipes that lead to success. They are in an svn repository in a combination of xml and html.
- Many of the resource choices that podlings have made are now narrowed and normalized. Naming patterns are used. Mailing lists, SVN, Git, Jira, Confluence, and Releases can all be found by inspection once they are created.
- Many of the less usual processes like podling name changes are not well documented. Support for these can be improved.
Podling data not in
We have to decide how best to handle the data that is in the Podlings Status page and the Podlings YML file. We should narrow this down to what is critical to keep and then decide where it should go.
These items seem to be the most critical:
- SGA - the date that the SGA is received.
- ASF Copyright - the data that the donated code has had the copyright updated to Apache along with the License headers updated as appropriate.
- Distribution Rights - the date that the code and its dependencies have been confirmed to follow the Legal Policy on allowed 3rd party licenses.
- Issue Tracker - are issues tacked in JIRA or Github?
- Wiki - does the project have a wiki, and is it a Confluence Space or a Github wiki?
- News - while it should be able to track new committers and PPMC members automatically from the Roster page it makes sense to allow the podling to track other events. Releases can be detected as well and automatically added.
- Proposal - this url is not always the same as the podling name.
- Name change information - there is INCUBATOR-199 which requests adding more explicit information about name changes to podlings along with improvements to resolutions.
There are design choice here. Do we fold all of these additional pieces of information into
podlings.xml, or do we normalize the Podling YML file to only include these fields. A third option is to replace the Podling YML with a data file in another format.
Eliminating the need to hand edit files without removing the ability is a goal. Let's discuss the actions that need to be recorded. Work was started in this direction in Whimsy and this can be continued.
New Podling - begins incubation. This adds the
podling record to
Podling Roster / Status - this page exists and currently handles roster changes. It could be expanded to cover updates:
- IP related events
- Reporting information
Also, the page can show the clutch analysis for the podling.
Rename Podling - this expensive operation needs to be discouraged, but when it is needed appropriate guidance should be provided.
Exit Incubation - a page that covers the several transitions a podling may make as it exits the Incubator by graduating or retiring.
The Incubator site can be simplified as follows:
- Remove the podling status pages under
- Improve the
/projects/ page to be the place to find deeper status with links to Whimsy pages for the podling. Each podling has an anchor in the tables.
- Change the site's
.htaccess file to redirect project links to the anchor.
- Remove the clutch analysis pages since the information will be on the Whimsy page.
The Podling Status pages in xml will no longer be updated nor will they be shown. They can remain in svn for archival purposes.
The checklists should be moved into the Cookbook
