CimHarvest.java already deals with component input sources, but not file input sources. The following tag snippet shows a <type value="File"> tag for boundaryCondition that needs to queue different handling of the <couplingSource> tag:

<coupling fullySpecified="true" purpose="boundaryCondition">
            <description></description>
            <type value="File"/>

In this case the couplingSource is a file and should map to the triple predicate "hasInputDataset" instead of "hasInputSourceComponent".

The record to populate the "hasInputDataset" is the "dataObject" record. The "fileName" should be linked to "hasInputDataset":

<dataObject dataStatus="complete">
        <acronym>file_solar</acronym>
        <description>Annual mean variations in total solar irradiance (TSI) are partitioned across six shortwave spectral bands (0.2-10&#956;m) to estimate the associated spectral changes with TSI variations (Lean et al., 1995). With the changes across the spectral bands the Rayleigh scattering and ozone absorption properties are also varied. The TSI data used for the historic period were recommended by CMIP5 (Lean et al., 2009 -L09; SOLARIS 2009) and are created from reconstructions of solar cycle and background variations in TSI. The annual mean TSI was processed to force the mean of the 1700-2004 period to be the same as the model control solar constant value (1365 Wm-2). </description>
