I’d say it is - look at the comment block at the top of the files 
I think rahatmaini has just taken Paul’s library changed the directory structure and added some meta files to “contribute” it to Build.

ooohhh… one of THOSE code streaks. Well yes if I can help @peekay123 in bringing the Library back up to snuff it will go a along way to helping my own project move along; Currently I cant even get the board recognized though the Arduino picks it up; Im working back over stuff which no doubt Peekay123 has already trundled over in the past.
@loudmouthman, often a device not being recognized is caused by wiring. That (and many other) libraries need some lovin. I’d be glad to help!
@peekay123 I shall take you up on that offer; I found the original longer thread on the topic of NFC and your work pulling it all forward; Ive ensured my wiring reflected this ; My NFC reader board looks just like the red one in the picture and its reading on the Arduino okay; so looking at the readmifareClassic code it looks like D3 and D4 are used in place of D0,D1 ( probably some ‘contributing there as @ScruffR suggested’ ) Ive attempted various cable swaps I may go down the pull up route with the resistors though its not required on the arduino it might be needed for this board. Im going to take a break for tonight as I have been in and out of the build screen for most of the afternoon. I shall come back with some photos of the configuration and also look at maybe adding a 10K pull up on the circuit as it appears to be suggested in at least one of the photos.
@loudmouthman, the pull-ups are ABSOLUTELY necessary with Particle devices (Arduinos have them onboard). You can use 4.7K or 10K ohm resistors. Make sure to pull the up to the Vcc of the NFC board (most likely 5v) and be sure to have the Photon and NFC grounds tied.

Excellent I shall get on with that in the morning and in the meantime I’ll kick off the converasation going forward over there: PN532 NFC Library [PORTED] on the Thread which I was looking at.
