| *Title* \\ | _Common validation error messages from PDF to PDFA conversion_ \\ |
| *Detailed description* | The validation error messages found from two pieces of validation software when performed on the same [file:\\]From PDFBox Preflight: \[file: \\
From PDFBox Preflight: \\
Invalid font definition \\
Syntax Error: invalid float range in Number operand \\
Invalid color space... \\
From Adobe Preflight \\
CIDset in subset font is incomplete \\
Font not embedded \\
Syntax problem: Real value out of range (too high) (also commonly get the other extreme - too low) \\ |
_A detailed description of the Issue. The Issue_ *{_}MUST{_}* _focus on the busines or preservation driven challenge, and should not assume or prescribe a particular solution. Describe what the Issue is, why you have the Issue, and what your requirements are for a Solution. For example, it might be important that a technical solution runs on UNIX, or has a GUI front end and is easy to use, or needs to process records efficiently as the Dataset is large._ |
| *Issue champion* | _Who owns the issue? Type "\[" and then your name to use autocomplete. _{_}This creates a link to your user profile on the wiki, including your contact details, so is the best way to add your name.._ |
| *Other interested parties* \\ | _Any other parties who are also interested in applying Issue Solutions to their Datasets._ |
| *Possible Solution approaches* | _Brief brainstorm of possible approaches to solving the Issue. Each approach should be described in a single sentence as part of a bulleted list. Further detail can go in a dedicated Solution page._ \\ |
| *Context* | _Details of the institutional context to the Issue._ \\ |
| *Lessons Learned* | _Notes on Lessons Learned from tackling this Issue that might be useful to inform digital preservation best practice_ . \\ |
| *Datasets* | _Reference to the appropriate Dataset page, by hyperlink. Note that all Issues_ *{_}MUST{_}* _be linked to at least one Dataset\!_ \\ |
| *Solutions* | _Reference to the appropriate Solution page(s), by hyperlink._ |
| *Issue champion* | [~jog]  |
| *Other interested parties* \\ | \\ |
| *Possible Solution approaches* | Interested in seeing which conversion software can handle these errors when trying to convert to PDFA1b \\ |
| *Context* | \\ |
| *Lessons Learned* | Different software produces similarly named errors which may or may not be equivalent \\ |
