To update a blog post, complete the following steps:

1. Retrieve the Blogs service document. See Retrieving the Blogs service document.
2. In the service document, find the workspace for the blog from which you want to retrieve the post,and then retrieve the web address of the "weblog Entries" collection in that workspace.
3. Send a GET request to the weblog Entries collection.
4. In the returned feed, find the entry and note down the value of the href attribute of its <link rel="edit" type="application/atom+xml" ... > element.
5. Send a PUT request to the web address defined in the href attribute and pass in a new blog post entry document that includes your changes.
Owner can always edit the content regardless the status.
  • Allow community owners to graduate an idea

  • Owner can just resubmit the entry document with: <category scheme="" term="graduated" />
    When an idea is graduated, the entry document's category flag is changed to :
    <category scheme="" term="graduated" label="Idea has graduated" />
  • An option is provided to create an activity (use Activities's atompub API)

  • In order to create or link an activity, the idea must be in graduated state.
    User will need to pass in the URL parameter createActivity=true to ask Blogs to create the activity when graduate the idea.
    If the activity widget doesn't exist we will create it.
    There will also be an option to map the ideationblog to an existing activity, to do this
    use the rel=""above without the createActivity=true parameter
    we will check to see if it has already mapped to the same activity, if it is not then update it or add it if new
  • An idea can be ungraduated

  • To ungraduate an idea, delete the term="graduated" category.
    Make sure when you resubmit the entry document to an UPDATE, DO NOT REMOVE THE graduated term catergory if you have one and not intended to ungraduate it.
    Ungraduate idea will not have an "ungraduated" indicator, if term="graduated" is not found, then assume it is an ungraduate idea.
