Kunzwisisa Metadata: Mashoko Akavanzwa mu Photo Files
Mubvunzo: Chii chinonzi Metadata?
Nezve EXIF, IPTC uye XMP Metadata Inoshandiswa mu Graphics Software
Mhinduro: Metadata ishoko remashoko anotsanangurwa akaiswa mukati memufananidzo kana rumwe rudzi rwefaira. Metadata iri kuwedzera kukosha munguva ino yedhidhiyo mifananidzo apo vashandi vari kutsvaga nzira yekuchengetedza ruzivo nemifananidzo yavo iyo inoshandiswa uye inogara nefaira, zvose iye zvino uye munguva yemberi.
Rumwe rudzi rwemetadata ndeye ruzivo rwekuwedzera iyo inenge dzose makamera ejedi akachengetedza nemifananidzo yako. Metadata yakatorwa nekhamera yako inonzi DIF data, iyo inomirira Exchangeable Image File Format. Nyaya yakawanda yejeri yefaira inogona kuratidza mashoko EXIF kumunhu, asi kazhinji haigadziri.
- Zvose Nezveruzhinji EXIF Information muDhijhori Photo Files
Zvisinei, pane mamwe marudzi emetadata inobvumira vashandi kuwedzera yavo pachavo mashoko anotsanangurwa mukati megodhi yemufananidzo kana faira remufananidzo. Iyi metadata inogona kusanganisira maitiro emufananidzo, ruzivo rwekodzero, zvinyorwa, zvikwereti, mazwi makuru, zuva rezvisikwa uye nzvimbo, ruzivo rwemashoko, kana mirayiridzo inokosha. Zviviri zvemasetata zvinowanzoshandiswa zvakagadzirirwa mafaira ezvifananidzo zviri IPTC uye XMP.
- IPTC ndiyo yakagadzirwa mumakore ekuma1970 ne International Press Telecommunications Council. Chakanga chave chichigadzirwa sechiyero chekutsinhanisa ruzivo pakati pemasangano emashoko uye yakave nekufamba kwenguva. Munenge muna 1994, fomu yeAdobe Photoshop ye "Fomu Ruzivo" yakagonesa vashandisi kuisa nekugadzira IPTC metadata mufaira dzemifananidzo dzedhijidhi uye saka yakagamuchirwa nemasangano emifananidzo ekutsvaga uye mamwe mabhizinesi ekubudisa mabhuku kunze kwemashoko ezvenhau.
- XMP ndiyo itsva ye XML-based "Extensible Metadata Platform" yakagadzirwa neAdobe muna 2001. Adobe akashanda ne IPTC kuisa yekare "IPTC musoro" muchirongwa che XMP itsva uye muna 2005 "IPTC Core Schema yeXMP" tsanangudzo yakabudiswa . XMP inzvimbo yakasununguka, inowanikwa yevanhu vose, zvichiita kuti zvive nyore kune vakugadziri kutora mutsara mune wechitatu-party software. XMP metadata inogona kuwedzerwa kune dzakawanda mafaira emafaira , asi pamifananidzo yakajeka, inowanzochengetwa mumafaira eJPEG neTIFF .
Zvizhinji zvehuwandu hwekugadzira mifananidzo nekufananidzira kwemazuva ano zvinopa mikana yekuiswa uye kugadzirisa metadata mumafaira ako emufananidzo, uye panewo humwe hutano hwakakosha hwekushanda nemhando dzose dzemetadata kusanganisira EXIF, IPTC, uye XMP. Vamwe vekare software haibatsiri metadata, uye iwe unotadza kurasikirwa nemashoko aya kana iwe uchigadzirisa nekuchengetedza mafaira ako ane metadata akabatanidzwa muchirongwa chisingaatsigi.
Pamberi pemitemo yemetadata, mifananidzo yese yekuchengetedza mifananidzo yakanga ine maitiro avo chaiwo ekuchengetedza ruzivo rwemifananidzo, izvo zvaireva kuti ruzivo haruna kuwanika kunze kwee software - kana wakatumira mufananidzo kune mumwe munhu, mashoko anotsanangura haana kufamba nawo . Metadata inobvumira kuti ruzivo urwu ruendeswa nefaira, nenzira inogona kunzwisiswa nedzimwe software, hardware, uye vashandisi vekuguma. Inogona kutotamiswa pakati pefaira mafaira.
Photo Sharing uye Metadata Kutya
Munguva pfupi, nekusimudzirwa kwechifananidzo kugoverana mumagariro evanhu se-Facebook, pane kuve nokutya uye kunetseka pamusoro pehupenyu hwehupenyu hwepanyika sehwaro hwekugara hunoiswa mumetadata yemifananidzo yakagoverwa paIndaneti. Izvo zvinotyisa zvinowanzove zvisina ruzivo, zvakadaro, sezvo dzose dzemasangano makuru evanhu dzinobatanidza metadata dzakawanda dzinosanganisira nharaunda yekodzero kana hutano hweG GPS.
