> These are my findings so far:
> Using the new gapText parameter in UIMA Ruta HTMLConverter I noticed that the string is trimmed in the pipeline aggregation process e.g. “   .   “ ends up as “.” in the pipeline and when writing the pipeline to XML. I don’t think it has anything to do with the HTMLConverter in particular. We use UIMAfit to construct the aggregated analysis engine description but I don’t know where this trimming exactly occurs. I was also able to run a small example pipeline where the trim did not happen, which was a bit of a surprise.
> The trimming is as such not a technical issue for me right now but I felt it might become important in some other case. I just noticed it when I added ekstra spaces to improve readability of my output. Initially I thought it was the HTMLConverter but when I inspected it then I could see that it had happened somewhere before configuration parameter initialisation.
> I then inspected the UIMAfit generated descriptor right after creation. The value was not trimmed at that point. Later during runtime initialisation without doing any XML serialization this time, the value is trimmed inside ConfigurationManagerImplBase::getConfigParameterValue right after the lookup operation (used debugger for value inspection). This was inside a UIMA core component though but the trim occurs somewhere between descriptor creation and AE initialisation. Seems this is not an UIMAfit issue afterall.
> I did a small example app where the HTMLAnnotator and HTMLConverter descriptors were also aggregated before execution but here the trimming did not materialise at runtime but only in the serialised XML. Then it occurred to me that my example used the SimplePipeline whereas our main application uses CPE. I then switched to the SimplePipeline and the trimming was now gone there as well. Seems that trimming only happens inside the CPE and when XML serialising the pipeline.
