The reading order is in my experience only correct, if the text is linked.
When it comes to alternative text. You draw the out of the image meta information view Object export settings. Is that right? Does it fil with any file type or only with JPG or TIF or a specific kind. With captions there was a problem in the past that JPG's captions from its meta was ignored, so I had to work with PDFs.
Or are you sure that the textual information is written into the image itself or only to the database of Bridge or Lightroom. Make sure that this information is part of the image itself.
I'm not sure what you mean by if the text is linked. According to the instructions provided by Adobe, you create your paragraph styles and set your tags (h1, h2, h3, p, etc.), and then use the articles panel to set your reading order, both for text and images.
Yes, alternate text is set in the Object Export Options dialogue box, placing the alternate text both in the Alt Text tab and the Tagged PDF tab. The issue has been experienced with a variety of file types including jpg, png, tif, and ai files.
I am not using Bridge or Lightroom. Links are set to the images in the appropriate file directories, and alt text is set within the Object Export Options dialogue box within InDesign, and not within the meta data sections of other applications.
Text is linked when it is not in different stories, but in the same text thread. The article panel is not respected when it comes to the reading order in a PDF, only in EPUB export.
Try to edit the meta data in Bridge and draw that information into InDesign via the Object Export settings set up to meta information. I think you will be much faster that way, and try it, if it would work better that way.

Not according to Adobe: "The article panel is not respected when it comes to the reading order in a PDF, only in EPUB export." ... "The article panel is not respected when it comes to the reading order in a PDF, only in EPUB export." -Creating accessible PDF Documents
I don't use Bridge for image management and am typically pulling from a large collection of imagery from a shared server used by other designers and creatives in different departments.
The correct quote did not post from Adobe. Apparently my Ctrl hotkeys are not working in Chrome...
Adobe: "InDesign CS5.5 introduced the Articles panel, which makes tagging PDF documents easier than ever — you no longer have to use the Structure pane or Tags panel." ... "Articles provide designers and production artists an easy way to create relationships among page items. These relationships define the content to be used while exporting to ePub, HTML, or accessible PDFs, and define the order of the content." -Creating accessible PDF Documents
The Articles panel in InDesign absolutely can control the tag order of elements (reading order) when used. If you use the articles panel, you need to make sure that you also choose "Use for Reading Order in Tagged PDF" from the Articles panel menu. You don't have to thread the text to control the reading order although the Articles panel doesn't allow you to insert an image in the middle of an existing text story. You still need to anchor the image to make that work.
Regarding the alt text, I've not encountered this inconsistency that you are describing. Which specific version of InDesign are you using? I know you said CC 2015, but I'm curious which release.
I do have use for reading order in Tagged PDF checked, but the order is still off fairly regularly after export to Acrobat. As far as the version, this is the 2015.4 Release, 126.96.36.199 x64 Build.
For the life of me I cannot figure out why the alt text makes it with some images, and not with others. Another, annoyance related to alt text is that sometimes Acrobat sees one image as two. It will have alt text for the image, but then there is a highlighted blank area, usually to the left of the image that is the same size that it recognizes as an image in need of alt text as well. I'm thinking it has to be some sort of bug (all of these issues probably are) that is fixed by marking the blank an artifiact, but I really should not have to take the time to do that. :/
I have the same issue, in CS6, Mac. Only one of 3 images with alt text assigned, makes it into Acrobat showing any alt text.

This is a known bug: some graphics with Alt-text in InDesign will be missing their Alt-text in the exported PDF. It's a mis-tagging of the graphics that you can see if you delve into with the Contents panel in Acrobat, if you really want to go that deep!
No known pattern that triggers the problem: doesn't matter if the graphics are anchored or not, whether the Articles panel has been used at all, or set to use the Articles panel for the reading order.
No known workaround at this time, other than rewriting the Alt-text on those graphics in Acrobat Pro.
I am having the same issue in my latest large book (300+ pages). I've isolated it to vector figures (ai, eps) and editable pdf figures. I can export the pdf, and using the reading order accessibility tool I can "see" my alt text, but when I get out of the tool, the figures act as if they are artifacts (i.e, they are not selectable) so I can't manually add the alt text. The alt text on the tifs comes across just fine, but not the eps and pdf figures. As someone above mentioned, these figures need to be edited frequently, so making new versions, rasterizing them, replacing the vector versions, and keeping track of everything would be a nightmare.
I will go deep...
I'm not sure what you mean when you say they are not selectable. You can only select them when you have the Reading Order tool active. Click on the label (number or tag) for the figure and then right click and choose "Edit Alternate Text". I prefer to add the alt text by selecting the tag for the figure in the Tags pane, right-clicking on the tag and choosing properties. Then you can add the alt text this way as well.
I've not encountered this missing alt text in my files although I have encountered it when applying alt text in InDesign to nested groups of objects.
This may be difficult to visualize, but the alt text on vector figures already shows up when the Reading Order tool is used, just as it does for raster files, but in the standard view of the pdf you cannot click on a vector figure (eps or pdf) to read the alt text…it behaves as if it is an artifact; whereas the alt text for rasters shows up when you click on the figure. No matter if it’s a vector or a raster, when clicking on the figure using the Reading Order tool, I get the box with the giant X and the black alt text box that says “Figure – ”.
The order menu shows the vector figures as “image”. The tag tree shows up as and underneath it “pathpathpathpath” (plus any words that are in the illustration)….
The document passes the accessibility checker. When I open the pdf in the current version of Acrobat Pro, if I wait a really long time, sometimes (doesn’t always work) I can select a vector figure (click on it) and see the alt text. When we open the document in Acrobat Reader DC (which is what most of our people use) the alt text doesn’t show up on the vector figures at all. Our alt text needs to be visually readable on screen by our users with low vision or those that may need assistance with color. This is in addition to alt text being available to readers using assistive devices.
Note: The alt text on raster figures shows up just fine. No matter which view I use.
During this phase of the process, my project leader needs to review the alt text for accuracy. I do not want to go through 305 figures and copy the alt text out of each individual object export screen into a text document for him. Is there at least a workaround that will allow me to make the alt text visible to sighted readers while the draft is sent out for field review?
